• Grayscale
• Blend (AddScalarToGray, AddGray, AddGrayWeighted)
• Threshold (Binary, BinaryInv, Trunc, ToZero, ToZeroInv, Otsu)
• Image padding (BorderConstant, BorderReplicate, BorderReflect)
• Convolution
• Blur (Average - Box, Gaussian)
• Edge detection (Sobel, Laplacian, Canny)
• Resize (Nearest Neighbour, Linear, Catmull-Rom, Lanczos)
• Effects (Pixelate, Sepia, Emboss, Sharpen, Invert)
• Transform (Rotate)
• Generate (LinearGradient, SigmoidalGradient)
