abstract: In this paper we describe an image sensor
with nonuniform pixel placement that enables a highly efficient
computation of the Discrete Cosine Transform, which is the most
computationaly demanding step of the image compression algorithm. This
technique is based on the Arithmetic Fourier Transform (AFT), which we
show to be 5 times more computationaly efficient than currently used DCT
computation methods. The architecture and circuits described can be
implemented in conventional CMOS processes.
