I am trying to detect body from images using haar cascades. I am using python code in order to do so, my code is the following:
import numpy as np
import sys
import cv2
body_cascade = cv2.CascadeClassifier('cascades/haarcascade_upperbody.xml')
img = cv2.imread('body/body4.jpg')
gray = cv2.cvtColor(img, cv2.COLOR_BGR2GRAY)
faces = body_cascade .detectMultiScale(gray, 1.1, 8)
for (x,y,w,h) in faces:
cv2.rectangle(img,(x,y),(x+w,y+h),(0,255,0),2)
roi_gray = gray[y:y+h, x:x+w]
roi_color = img[y:y+h, x:x+w]
I ve tested several images, the three cascades for body several scalefactors. However, it seems not finding the body in any image. Am I doing something wrong in the parameters of detection? When I tried frontface cascades everything worked fine.
