QUESTION
I currently face a problem when I want to call a class A method inside a class B method. The code is running fine. However, the problem happen at line 73 in ImageProcessing.py where MainApplication.signup() is asking for parameter. This function is built for returning to the signup page. I am not sure if it is the right way to code like this. Please help me. I would appreciate your kindness.
*This is Display.py
...ANSWER
Answered 2022-Feb-18 at 17:39You cannot call the method, because it is not a static / class method but instead the method of an instance / object of the class MainApplication.
This means that the cancel_it method's parameter self expects an instance of the class MainApplication to function properly but by calling MainApplication.cancel_it() it receives the class instead as argument and therefore throws an exception.
You could easily call it, by passing a reference to the Mainapplication-instance to your cancel_it method.

I have uploaders for different types of images. Each has the same set of derivatives (large, medium, thumbnail), but different resolutions. But they also share some configuration. For example, each uploader converts the original to jpeg, changes quality and strips metadata.

Answered 2021-Dec-12 at 09:13There isn't anything for sharing processing logic out-of-the-box, but you can create a service object, for example:

I am trying to write a code for contrast but contrast depends on threshold value.What I mean is using entered threshold value or if it is not entered by user I want to write a default value for threshold.As far as I know I should do this by using constructor but I am not good at object oriented programming.How can I do that?
Here is the code for Form1.cs:

I am trying to linearly scale an image so the whole greyscale range is used. This is to improve the lighting of the shot. When plotting the histogram however I don't know how to get the scaled histogram so that its smoother so it's a curve as aspired to discrete bins. Any tips or points would be much appreciated.
...ANSWER
Answered 2021-Nov-02 at 14:07I'm not sure if this is possible if you're linearly scaling the image. However, you could give OpenCV's Contrast Limited Adaptive Histogram Equalization a try:

I am facing a weird thing here. I have installed Tensorflow on Ubuntu 20.04 locally. I have created a virtual environment (I don't use conda) in vscode. The tensorflow installation was made with pip as shown on the official Tensorflow site.
...ANSWER
Answered 2021-Sep-19 at 09:54Try using from tensorflow.keras import
Importing tensorflow as tf creates an alias of tensorflow as tf for your file () only. Where as you're importing keras from a library named tf which isn't there.
It's not a "Python Issue", Hope it helps.

QUESTION
I'm pretty new to Python and opencv, and I would like to use opencv to crop frames from a video. The work flow is as follows: I opened up an image and get some coordinate values from mousecallback function. Since the video was taken with a cell-phone on a tripod, I would expect the region of interest should be fixed in space. Therefore, I can use the coordinate to batch process other frames. The first cropped image is done and saved as expected but I have a problem processing the other frames.
Code imported packages ...ANSWER
Answered 2021-Jun-12 at 03:48I can't test it but I think I see problem - you mess with coordinates.
get_cropped() returns

Recently I upgraded from Rails 6.0.3.4 to 6.1.3. ActiveStorage deprecated combine_options, which I cleared from my app. All fresh request work as expected.
Internet Bots (Facebook, Google, ...) cache urls to images hosted on a website (like mine). According to my Rollbar records they request these a couple of times a day.
The cached URL's that should load ActiveStorage attachments include an old variation_key in the URL. When the blob wants to load using the decoded variation_key, I see that combine_options is still present. This throws a 500 Internal Server Error with ArgumentError (Active Storage's ImageProcessing transformer doesn't support :combine_options, as it always generates a single ImageMagick command.):.
Is there any way I can stop these errors from showing up?
Rails version: 6.1.3. Ruby version: 2.7.2p137
...ANSWER
Answered 2021-Mar-08 at 10:42I have resolved this issue using some middleware. This will intercept all incoming requests, scan if they are ActiveStorage urls, find the ones with the deprecated combine_options and just return 404 not found. This code will also raise an error is the current environment is development, this way I don't accidentally introduce the deprecated code again.
For those of you who might have the same problem, here's the code.

QUESTION
can anyone help me understand using conda environment with visual studio code? I had activate the virtual environment (imageprocessing) with this:
...ANSWER
Answered 2021-Feb-03 at 08:38In VS Code, when we use different python environments, the locations where the modules are installed are different. Therefore, we need to be clear which python environment we are currently using. (We could check it with the command "python --version" in the VS Code terminal.)
When we use the conda environment, it comes with python, so we can use "pip" to install modules, or "conda" to install modules. The modules it installs are stored in: "...\anaconda3\envs\conda-name\lib\site-packages".
The command "pip show pillow" checks the installation position of the module:
In addition, after the installation is complete, it still shows that the module cannot be found. I noticed that there is a problem with the file name here. We need to rename "PIL" to "pillow", or use "import PIL"
Reference: conda-environment in VS Code.

Install imageProcessing
You can use imageProcessing like any standard Java library. Please include the the jar files in your classpath. You can also use any IDE and you can run and debug the imageProcessing component as you would do with any other Java program. Best practice is to use a build tool that supports dependency management such as Maven or Gradle. For Maven installation, please refer maven.apache.org. For Gradle installation, please refer gradle.org .
