The code check a dot is in a polygon region or not

Code:

import matplotlib.path as mplPath
def check_in_roi(bbox, roi, rw, rh):
    x1 = bbox[0]
    y1 = bbox[1]
    x2 = bbox[2]
    y2 = bbox[3]
    feet_dot_x = int((x1+x2)/2)
    feet_dot_y = y2

    temp = []
    for c in roi:
        temp.append([c[0]*rw, c[1]*rh])

    roi_path = mplPath.Path(np.array(temp))
    if roi_path.contains_point((feet_dot_x, feet_dot_y)):
        return True
    else:
        return False

input roi should be a list of dot [x,y]
