lumin | JavaScript library to progressively highlight | Text Editor library

I'm trying to write video analysis software to check compliance with WCAG 2.0 seizure guidelines. But, in the definition of 'general flash', it states the following:

A general flash is defined as a pair of opposing changes in relative luminance of 10% or more of the maximum relative luminance (...)

I am confused about the usage of "maximum relative luminance". It's not specified in which context we are considering the maximum. Does it refer to 1.0 luminance? Or the maximum luminance achieved in the webpage? Or something else?

I couldn't find any clarification. I would just assume that it refers to 1.0 luminance, but, if that assumption were wrong, my code would produce false negatives in flash detection due to an incorrectly high threshold.

Sorry if I'm missing something obvious or if this is the wrong place to ask.

I have created my own color using the following command:

The design

I'm trying to implement a RGB to YUV444 conversion algorithm in hardware based in the next approximation I've got working in a C based program:

I am cathing one API and I cannot deserialize a JSON property and I do not know where is the problem.

So I have an object from convertJSON2CSharp :

I am new to python and I am trying to visualize a .txt file. I tried visualizing it using NumPy arrays. I had success normally using matplotlib and plotting it, but I want to try visualizing it normally with its own high quality without plotting or converting it to the image format as it would change the values to 0-255. These values are not pixel values but are luminance values. How can I achieve it? Any help is truly appreciated. Thank you so much in advance.

So i am practising a project through a course.And one of the project is based on color palletes where the site generates random palletes with an additional functionality with which user can change hue,brightness,saturation I am somewhere midway but my sliders don't function as desired. If i change the hue the background doesn't change according it keeps revolving around some greyish color and somehow saturation of all colors is stuck at the start. I checked if the scale for hue is correct or not. I tried checking console.log into arrays to check if every initial colors is getting pushed correctly but that seems correct

Please help Thanks in Advance

Here's the code

I've written a procedure called gray_scale that is suppose to have an input TImage component, turn the image that it contains into gray scale and then print it in the same TImage component. The issue with it is that it prints an black image. My code is below, please note that I've created a local variable called img2: TPicture which purpose is to be like a middle stage between the input and the output of the procedure.

Gnuplot is a very powerful library that supports plotting of functions with numerous scientific operations. What my case is I want to read a single channel grayscale image just as we read in matlab or python using imread and store it into a 2D data grid using gnuPlot.

Basically I want to make contours of image gray scale intensities.To do that I am exporting the single channel luminance data of the image as a .dat file using matlab once it is exported I splot it using:

Gimp has a "Luminance" mode in the layer settings:

I use it to overlay a high-resolution grayscale image on an upscaled low-resolution color image to make the color image sharper. E.g., given a grayscale image and a color image

,

the result of applying the grayscale image as a luminance "mask" on the blurry color image creates a sharp color image:

How does the luminance filter work, and how would I implement this in Python (e.g. using Pillow)?
