I created my own Haar Cascade Classifier for detecting cows. The code works perfectly fine for the available OpenCv xml files but shows the following error when I run it using the xml file that I created.> Traceback (most recent call last): > File "C:........\Haar> Cascade\cow_detect_image.py", line 11,> in < module >>> cows => cow_cascade.detectMultiScale(gray,> 1.3, 5) >TypeError: Incorrect type of self (must be 'CascadeClassifier' or> its derivative)
**Here's the code:**
> import numpy as np >import cv2>>> cow_cascade => cv2.CascadeClassifier('cow.xml')>> img = cv2.imread('Cow3.bmp') >gray => cv2.cvtColor(img, cv2.COLOR_BGR2GRAY)>>> cows => cow_cascade.detectMultiScale(gray,> 1.3, 5)> for (x,y,w,h) in cows: > cv2.rectangle(img,(x,y),(x+w,y+h),(255,0,0),2)> roi_gray = gray[y:y+h, x:x+w] > roi_color = img[y:y+h, x:x+w]> cv2.imshow('img',img) >cv2.waitKey(0)> cv2.destroyAllWindows()
**What is wrong and how can I fix this?**
