Finally, let’s try annotating images with text. To do this, use the putText () function in OpenCV. Have a look at its syntax, followed by the arguments: putText (image, text, org, font, fontScale, color) As usual, the first argument is the input image. So, first you can try downsampling the input images twice. Also your text looks bit tilted, so you can try rotated rectangle instead of the upright rectangle. Then you can tune the parameters for your case. As I have mentioned in the code, the contour filtering criteria isn't very robust. shark tank india latest episodes
