I'm developing a website for a university project.

I need to apply custom kernel to a image, i can do this very easily with python but I am struggling to do it in javascript

gray = cv2 . cvtColor(image, cv2 . COLOR_RGB2GRAY)
kernel = np.array ([
    [ -1 ,0 ,1] ,
    [ -2 ,0 ,2] ,
    [ -1 ,0 ,1] ])

cv2 . filter2D (gray, -1,   kernel_vertical)

I want to do something like this but in javascript.

I started by taking a look at these exemples: https://docs.opencv.org/master/dd/d6a/tutorial_js_filtering.html

but they don't show to to use a custom kernel, can anyone help?
