Handles RGB/BGR/Grayscale conversions transparently, applies transforms in appropriate color spaces (e.g., HSV for hue shifts, LAB for perceptual uniformity), and converts back to original space without color artifacts.
Unique: Automatically handles color space conversions (RGB↔HSV, RGB↔LAB) for color-aware transforms, applying operations in perceptually appropriate spaces and converting back without artifacts; supports both uint8 and float32 images with automatic range handling
