So I first need to read the image file of student ID card get the edges of the ID card and draw a rectangle covering the edges and the crop the detected edges of the image.
These are the methods I used so far
--> To read the image file - imread()
--> To convert to grayscale - rgb2gray()
--> To detect the edges - edge() using the Canny method
--> To get only edge data - bwconvhull()
--> To draw the rectangle over the ID - regionprops
These are my main idea the solutions works but its not that accurate. Pls if somebody knows it that would be really helpful
