QUESTION
I've been working on a Laravel 8 application, and recently I've been working on the security of the app. I've elected to authenticate users "manually" - as in not using the starter kits available - and have something where I can create a user and have them log in to the application.
The issue I'm having is that upon a successful log in attempt, I'm given the following error:
SQLSTATE[42S22]: Column not found: 1054 Unknown column '' in 'where clause' (SQL: select * from
users
where `` = 11 limit 1)
This error occurs once the credentials have been matched to what's on the database. I'm assuming the unknown column is id
given that the current user I'm trying to log in as has the id of 11, which would fit with the SQL query in the error.
The user table schema is as follows:
The user model is as follows:

QUESTION
I am getting confused with the filter paramater, which is the first parameter in the Conv2D() layer function in keras. As I understand the filters are supposed to do things like edge detection or sharpening the image or blurring the image, but when I am defining the model as
...ANSWER
Answered 2021-May-07 at 18:10The filters
argument sets the number of convolutional filters in that layer. These filters are initialized to small, random values, using the method specified by the kernel_initializer
argument. During network training, the filters are updated in a way that minimizes the loss. So over the course of training, the filters will learn to detect certain features, like edges and textures, and they might become something like the image below (from here).
It is very important to realize that one does not hand-craft filters. These are learned automatically during training -- that's the beauty of deep learning.
I would highly recommend going through some deep learning resources, particularly https://cs231n.github.io/convolutional-networks/ and https://www.youtube.com/watch?v=r5nXYc2wYvI&list=PLypiXJdtIca5sxV7aE3-PS9fYX3vUdIOX&index=3&t=3122s.
QUESTION
I'm trying to make sharpness filter in Haskell using JuicyPixels. And I've made same Gaussian blur function and it works fine, but that one doesn't. These (Int, Int, Int)
tuples are my workaround for storing negative pixel values. T
means tuples there in names.
ANSWER
Answered 2021-Mar-30 at 22:01The short answer to your question is to use Double
or Float
instead of working with integral precision per channel. You are not gaining anything but this sort of overflow problems. Scaling [0, 255]
range to [0.0, 1.0]
should be the first step before you start doing image processing.
See my answer to your other question for more details on what you should do to improve your implementation. Here is also a proper solution to this problem as well:

...ANSWER
Answered 2021-Mar-19 at 15:50Your if
statement is quite ambiguous.
But one thing I'm sure of, Java IF statement
with a logical and &&
attempts to check the second condition only when the first condition is true
. It directly goes to else
block if it finds the first condition to be false
You can confirm this by running:

Answered 2021-Mar-18 at 16:43Change your values[0].trim() == "whatever"
lines to values[0].trim().equals("whatever")

tests if the strings reference the same object, not if their values are equivalent.
Also, see String.equals versus ==
QUESTION
I am trying to train a model on a data set which does not fit in my RAM.
Therefore I am using a data generator which inherits from tensorflow.keras.utils.Sequence
as shown below.
This is working. However because I am doing processing on the images my training is CPU bound. When looking in GPU-Z my GPU is only at 10-20% but one of my CPU Cores is at its max.
To solve this I am trying to run the generator in parallel on all my 16 cores. However when I set use_multiprocessing=True
in the fit() function the program freezes. And using workers=8
does not speed up the process just produces batches in uneven intervals.
ex.:
batch 1-8 is processed immediately than there is some delay and than batch 9-16 is processed.
The code below shows what I am trying to do.
...ANSWER
Answered 2021-Mar-12 at 09:53In the end I needed to make the Data generator use multi processing. To do this, the arrays needed to be stored in shared memory and than used in the sub processes.
QUESTION
I have experimented with two different methods of drawing the same shape, the first image is drawn by overriding JPanel's paintComponent(Graphics g) method and using g.drawOval(..) etc, The second image is drawn by creating a buffered image and drawing on it by using buffered image's graphics. How can I achieve the same rendering quality on both approaches? I have tried using many different rendering hints but none of them gave the same quality. I also tried sharpening by using Kernel and filtering, still couldn't.
...ANSWER
Answered 2021-Mar-08 at 04:39I found my solution by getting almost every setting of panel graphics and applying them to buffered image graphics. Here, the importing thing is that the panel's graphic scales everything by 1.25 and then scales down to the original before showing it on the panel.
Here is an example, -this is not exactly how my code is, this is just an example to give you an idea-
QUESTION
I have a code which gives me binary images using Otsu thresholding. I am making a dataset for a U-Net, and I want to try different algorithms (global as well as local) for the same, so that I can save the "best" image. Below is the code for my image binarization.
...ANSWER
Answered 2021-Mar-05 at 11:43The code of my solution got longer than expected, but it offers some fancy manipulation possibilities. First of all, let's the see the actual window:
There are sliders for
- the morphological operation (dilate, erode, close, open),
- the structuring element (rectangle, ellipse, cross), and
- the kernel size (here: limited to the range
1 ... 21
).
The window name reflects the current settings for the first two sliders:
When pressing s, the image is saved incorporating the current settings:
