Perfect for designers, artists and web developers for precise color. Step3: Convert image to HSV color space. It is difficult to use RGB (BRG in OpenCV) color space for color detection due to variations in lighting conditions and complex relationships between the three channels (R, G, and B). For example, let’s say we want to find a red apple in an image that has a green background. If you use his color detector, white will be recorded as 248, 248, 240, which is correct within the possible accuracy of Scratch color detection. You can modify his code to test first for 255, 255, 255 (or convert 248, 248, 240 to this value). 255, 255, 255 produces a pure white when redrawn while 248, 248, 240 is visibly off-white when redrawn.

Step 2 – Detect the color from the input image and create a mask: At first, we’ll detect green objects in this image and then we’ll detect yellow objects. OpenCV reads the frame as BGR colorspace.
