Hello, I have found the contours of the object in the image with a cv2.findContours and I want to clip the image in the extreme points. However, the image returned is not correct.
Below is the code, I have implemented. Any hint?
def clipping_image( image ):
'''
Clip segmented imaged based on the contours of the leaf
'''
image = cv2.cvtColor( image, cv2.COLOR_BGR2GRAY );
segmented, contours, hierarchy = cv2.findContours(image, cv2.RETR_TREE, cv2.CHAIN_APPROX_SIMPLE)
cnt = contours[0]
xmin = min(tuple(cnt[cnt[:, :, 0].argmin()][0]))
ymin = min(tuple(cnt[cnt[:, :, 1].argmin()][0]))
xmax = max(tuple(cnt[cnt[:, :, 0].argmax()][0]))
ymax = max(tuple(cnt[cnt[:, :, 1].argmax()][0]))
clipped = segmented[xmin:xmax, ymin:ymax]
return clipped
Thank you
