Convolving an image with a sequence of filter kernels is an important part of many image processing and computer vision applications. It often serves in the feature extraction process for classification tasks, pattern detection and recognition systems. This fundamental task is usually of high complexity for real-time systems, especially when an extensive set of large filter kernels are involved.

In this talk I'll introduce a family of filter kernels - the Gray-Code Kernels (GCK) and demonstrate their use in image analysis. Filtering an image with a sequence of Gray-Code Kernels is highly efficient and requires only 2 operations per pixel for each filter kernel, independent of the size or dimension of the kernel.
