I'm trying to crop an image using numpy. I'd like to divide one picture into nine and save it.
Write the function and enter the desired area and length to get the desired picture. However, I have to enter 9 times to get 9 photos. So I'd like to use repetition to get nine pictures if I enter it once. I tried to write using the for loop in the def, but it didn't work out, so I'm asking you this question. Thank you!
def crop(img, start_pos, length, width):
img_shape = img.shape
row = int(img.shape[0])
column = int(img.shape[1])
length = abs(length)
width = abs(width)
row = abs(row)
column = abs(column)
#for i in row()
#start_row = start_pos if start_pos >= 0 else 0
if start_pos >= 0:
start_row = start_pos
else:
start_row = 0
start_column = start_row
end_row = length + start_row
if end_row <= img_shape[0]:
end_row = end_row
else:
end_row = img_shape[0]
end_column = width + start_column
if end_column <= img_shape[1]:
end_column = end_column
else:
end_column = img_shape[1]
print("start row:" , start_row)
print("end row:" , end_row)
print("start column:" , start_column)
print("end column:" , end_column)
#print("divide:", divide)
#for i in row():
#row = row + 100
#if row <= img_shape[0]:
#print(row)
img_crop = img[start_row:end_row, start_column:end_column]
save = cv2.imwrite('C:/Users/USER/jupyter/crop_image/chicken_001_crop.jpg', img_crop)
return save
