Image Decimation and Interpolation Techniques Based on Frequency Domain Analysis
Tsuhan Chen, R. de Figueiredo · IEEE Transactions on Communications · 1984
A scheme for a spatial domain image data preprocessing decimation and postprocessing interpolation is presented. The scheme is implemented by appropriate FIR digital filters. Frequency and patial domain specifications are discussed in the design of the corresponding digital filters. Fast approximation techniques in the spatial domain are presented.
