Edge Detection using MarvinJ JavaScript












2















I am a beginner in Image Processing.I want to use MarvinJ javascript library to detect horizontal ,vertical and diagonal line (edge detection) given a image.
I have came across a lot of code examples which told that using prewitt one can do edge detection,like the one below.



function clickExampleFiltersEdge(){

    imageProcessed.clear(0xFF000000);

    Marvin.prewitt(imageOriginal, imageProcessed);

    Marvin.invertColors(imageProcessed, imageProcessed);

    Marvin.thresholding(imageProcessed, imageProcessed, 150);

    repaint();

}
