QUESTION
I would like to extract the definitions from the book The Navajo Language: A Grammar and Colloquial Dictionary by Young and Morgan. They look like this (very blurry):
I tried running it through the Google Cloud Vision API, and got decent results, but it doesn't know what to do with these "special" letters with accent marks on them, or the curls and lines on/through them. And because of the blurryness (there are no alternative sources of the PDF), it gets a lot of them wrong. So I'm thinking of doing it from scratch in Tesseract. Note the term is bold and the definition is not bold.
How can I use Node.js and Tesseract to get basically an array of JSON objects sort of like this:
...ANSWER
Answered 2021-Jun-15 at 20:17Tesseract takes a lang
variable that you can expand to include different languages if they're installed. I've used the UB Mannheim (https://github.com/UB-Mannheim/tesseract/wiki) installation which includes a ton of languages supported.
To get better and more accurate results, the best thing to do is to process the image before handing it to Tesseract. Set a white/black threshold so that you have black text on white background with no shading. I'm not sure how to do this in Node, but I've done it with Python's OpenCV library.
If that font doesn't get you decent results with the out of the box, then you'll want to train your own, yes. This blog post walks through the process in great detail: https://towardsdatascience.com/simple-ocr-with-tesseract-a4341e4564b6. It revolves around using the jTessBoxEditor to hand-label the objects detected in the images you're using.
Edit: In brief, the process to train your own:
- Install jTessBoxEditor (https://sourceforge.net/projects/vietocr/files/jTessBoxEditor/). Requires Java Runtime installed as well.
- Collect your training images. They want to be .tiffs. I found I got fairly accurate results with not a whole lot of images that had a good sample of all the characters I wanted to detect. Maybe 30/40 images. It's tedious, so you don't want to do TOO many, but need enough in order to get a good sampling.
- Use jTessBoxEditor to merge all the images into a single .tiff
- Create a training label file (.box)j. This is done with Tesseract itself.
tesseract your_language.font.exp0.tif your_language.font.exp0 makebox
- Now you can open the box file in jTessBoxEditor and you'll see how/where it detected the characters. Bounding boxes and what character it saw. The tedious part: Hand fix all the bounding boxes and characters to accurately represent what is in the images. Not joking, it's tedious. Slap some tv episodes up and just churn through it.
- Train the tesseract model itself
- save a file:
font_properties
who's content isfont 0 0 0 0 0
- run the following commands:
tesseract num.font.exp0.tif font_name.font.exp0 nobatch box.train
unicharset_extractor font_name.font.exp0.box
shapeclustering -F font_properties -U unicharset -O font_name.unicharset font_name.font.exp0.tr
mftraining -F font_properties -U unicharset -O font_name.unicharset font_name.font.exp0.tr
cntraining font_name.font.exp0.tr
You should, in there close to the end see some output that looks like this:
Master shape_table:Number of shapes = 10 max unichars = 1 number with multiple unichars = 0
That number of shapes should roughly be the number of characters present in all the image files you've provided.
If it went well, you should have 4 files created: inttemp
normproto
pffmtable
shapetable
. Rename them all with the prefix of your_language
from before. So e.g. your_language.inttemp
etc.
Then run:
combine_tessdata your_language
The file: your_language.traineddata
is the model. Copy that into your Tesseract's data folder. On Windows, it'll be like: C:\Program Files x86\tesseract\4.0\tessdata
and on Linux it's probably something like /usr/shared/tesseract/4.0/tessdata
.
Then when you run Tesseract, you'll pass the lang=your_language
. I found best results when I still passed an existing language as well, so like for my stuff it was still English I was grabbing, just funny fonts. So I still wanted the English as well, so I'd pass: lang=your_language+eng
.
QUESTION
When setRows()
run on an existing GridItem
, the generated Form GridItem
elements are fine, but the columns in the linked Sheet are reproduced in the next columns. The new columns are duplicates, but with a hidden property that shows that they belong to the Form (so we cannot delete the new columns). What is this property? The old columns are no more belong to the Form. The old columns may have existing values or previous Form responses.
How to prevent this?
The FormApp
should handles the sheet Ranges properly, by looking for the existing columns and just adds the real new columns with new array of strings.
How did the Google Forms UI handle this: When we use the Forms UI, we can easily add new rows in GridItem, and the link Sheet will be updated without duplicated columns.
Here is the Form to test, and please create a new linked response-Sheet before running the code:
Copy Sample Form with GAS code
Here is the GAS code:
...ANSWER
Answered 2021-Jun-15 at 09:35The process of manually editing a grid in a form with a linked sheet is as follows:
- You click the input box for the item.
- You update the text.
- The sheet will automatically replace the title of the corresponding column.
However, with Apps Script. The only process available to change a title, is to use the method .setRows
or .setColumns
. This behaves very differently from the UI. Esentially, it replaces the rows, and so, the linked sheet will generate new columns so as to preserve the previous answers.
It creates new columns because it has no way to know which new title corresponds to the old one.
For example, if you had some rows:
- A
- B
- C
When you get this from Apps Script, you have to first getRows()
QUESTION
I have a layout where I have two scroll views, one is a PageView
which is used to display a list of pictures horizontally, the second is a SingleChildScrollView
(maybe should be something else?), this scroll view is partially above the first one as initial position and can go completely over. Some screenshots to image this:
The problem is, if I make the 2nd scroll view take all page and add internal padding to it to make it the good height, the 2nd scroll view work as expected but the first one (witch is behind) isn't working anymore. The 2nd solution would be to wrap the SingleChildScrollView
with a Padding
widget to make it the good height and add Clip.none
parameter to the scroll view, but in this case the scroll view cannot be scrolled in PageView
zone even if the SingleChildScrollView
is over.
I wonder if someone already encountered a behavior like this and what is your solution.
Here my actual code with second solution:
...ANSWER
Answered 2021-Jun-14 at 13:46I found a little hack to do this, I passed the PageView
containing the photos inside the the SingleChildScrollView
so the PageView
is on top and can receive touch events, to keep the PageView
fixed to the top of the screen I use a Transform
widget that reverse the scrollOffset
of the SingleChildScrollView
.
(here the Transform
widget is also used to resize the PageView
containing photos when the scrollOffset
is under 0)

QUESTION
How can I send https request from one deployment to another deployment using AWS lightsail's private domain?
I've created two AWS Lightsail Container deployments using two docker images. I'd like to send https request from one image deployment ("sender") to another image deployment ("receiver"). This works fine when the receiver's public endpoint is enabled. However, I don't want to expose this service to the public but instead route traffic using AWS Lightsail's private domain.
My problem is when I try and send https request from "sender" to the "receiver"'s private domain (.service.local:) I get https://.service.local:52020/tester/status net::ERR_NAME_NOT_RESOLVED
on the "sender"'s html page. According to the Lightsail docs (section "Private domain") this should be accessible to my "Lightsail resources in the same AWS Region as your service".
I've found a similar Question & Answer in stackoverflow. I tried this answer using my region but failed because Lightsail container required https while .service.local required http. After creating a Amazon Linux instance, I succeeded making http request but failed to make https request. (screenshot below). In the meantime, Lightsail strictly asks you to use https.
If I force to send http request from https webpage, chrome generates Mixed content: The page at ... was loaded over HTTPS but requested an insecure ...
error. I can go around the https problem by using next.js api routes, but this doesn't feel secure because next.js api routes are publicly accessible.
Is there anything that I may be missing here?
Things I've verified:
- The image is up and running and works fine when connecting to it using the public domain
- I'm running both instance and container service in the same region
Thank you in advance.

...ANSWER
Answered 2021-Jun-11 at 00:54I made my two AWS Lightsail Containers, Frontend Container with next.js and Backend Container with flask, talk to each other using the following steps:
- Launch a Lightsail "instance" using "Amazon Linux" in the region I want to deploy my Container. Copy
/etc/resolv.conf
from this "Amazon Linux" instance. Update Dockerfile to overwrite/etc/resolv.conf
file in my docker. - To make API request using http instead of https and go around the
Mixed content: The page at ... was loaded over HTTPS but requested an insecure ...
error, I used next.js' API route to relay the API request. So, for instance, a page on Frontend Container will make API request to /api on the same Container and the /api route will make http request to Backend Container. - API route was properly coded with security measures so that users cannot use API route to access random endpoint in Backend Container.

This sounds like an easy task, but I already spent hours on it. There're several posts with a similar headline, so let me describe my problem first.
I have H264
encoded video files, those files show records of a colonoscopy/gastroscopy.
During the examination, the exterminator can make some kind of screenshot. You can see this in the video because for round about one second the image is not moving, so a couple of frames show the "same". I'd like to know when those screenshots are made.

I have an issue where [unowned self] was changed to [weak self] within the dataSource function used for a CollectionView using RxDataSource due to a memory leak. I now received a crash from returning a blank collectionViewCell that doesn't have a reuseIdentifier. I understand that I need to return a cell with a reuseID.
What changes are suggested to deal with this properly?
Someone suggested making collectionView.dataSource = nil in viewDidLoad() would fix this...
I was thinking instead of returning CanvasItemCollectionViewCell() in the 'guard' check, I return collectionView.dequeueReusableCell(for: indexPath, cellType: CanvasItemCollectionViewCell.self), but if self = self fails wouldn't that mean the collectionView is garbage?
This is a difficult problem to debug because this crash doesn't happen consistently.
