GoDIP (Go Digital Image Processing) is a simple image-processing library written in Go. It currently supports:

• Loading and saving PNG, JPG, GIF and PPM images
• Multi-channel, single-channel and float images
• Simple math operations
• Transformations: resizing, rotation, flipping
• Blurring: Gaussian and mean
• Convolutions (and generating some kernels like Gaussian or circular)
• Correction: changing brightness, contrast, gamma correction
• Edge detection using gradients
• Morphology: Min filter, max filter, dilatation, erosion, opening and closing
• Thresholding: using a single threshold or a range, gaussian adaptive thresholding
• Image types with convenient API allowing for simple creation of more filters
