'Regarding Multiple ROIs in an image using python/opencv
When you select multiple ROIs in an image, how to display them all simultaneously in that image white selecting one by one? How to deselect some selected ROIs in that image at the same instance of selecting ROIs? some of the code I have written below. Please modify and add the requirements.
If possible, please also help in changing the width and height of the selected ROI in the images itself.
path=r'D:\abc.jpg'
img_raw = cv2.imread(path)
ROIs = cv2.selectROIs("Select Rois",img_raw,0,0)
print(ROIs)
for roi in ROIs:
x1=roi[0]
y1=roi[1]
x2=roi[2]
y2=roi[3]
img_crop=img_raw[y1:y1+y2,x1:x1+x2]
cv2.imshow(img_crop)
cv2.waitKey(0)
cv2.destroyAllWindows()
