Examples of code experiments:

From PIL import Image,ImageFont, ImageDrawimport numpy as npimport colorsysimage = Image.open ("bryant.jpg") class_names =\ ["aeroplane", "bicycle", "bird", "boat", "bottle", "bus", "car", "cat", "chair", "cow", "diningtable", "dog", "horse", "motorbike", "person", "pottedplant", "sheep", "sofa", "train" "tvmonitor"] hsv_tuples = [(x / len (class_names), 1.1.) for x in range (len (class_names))] # get different chromaticity of hsv format colors = list (map (lambda x: colorsys.hsv_to_rgb (* x), hsv_tuples)) # get different colors of rgb format colors = list (lambda x: (int (x [0] * 255), int (x [1] * 255)) Int (x [2] * 1000), colors) # adjust the chromaticity of the corresponding borders of different categories through the hsv format font= ImageFont.truetype (font='simhei.ttf',size=np.floor (3e-2 * 1000 + 0.5). Astype ('int32')) # to obtain the font label =' {} {: .2f} '.format (' Lin Ma Zu Quan', 0.982) draw = ImageDraw.Draw (image) label_size = draw.textsize (label) Font) print ('label_size:',label_size) # label_size: (255,30) label = label.encode (' utf-8') draw.rectangle ([200,50,200 + label_size [0], 50 + label_size [1]], outline= colors [class _ names.index ('motorbike')], width=1,fill= colors [class _ names.index (' diningtable')] # for filling) draw.text ([200,50], label.decode (), fill= (255,0,0) Font=font) image.show ()
