import cv2

# Load pre-trained palm detection model
palm_cascade = cv2.CascadeClassifier('path_to_palm_detection_xml_file')

# Perform palm detection on input image
img = cv2.imread('input_image.jpg')
gray = cv2.cvtColor(img, cv2.COLOR_BGR2GRAY)
palms = palm_cascade.detectMultiScale(gray, scaleFactor=1.1, minNeighbors=5)

# Display detected palms
for (x,y,w,h) in palms:
    cv2.rectangle(img,(x,y),(x+w,y+h),(255,0,0),2)

cv2.imshow('Detected Palms', img)
cv2.waitKey(0)
cv2.destroyAllWindows()
