An Application of the Projection Transform Technique in Image Transmission

Projection transform technique is applied to digital image transmission. Transform samples on various central sections of a Fourier space are attained with a fast Fourier transform algorithm. Quantization, coding, and transmission follow in order. The complete Fourier space information is then, upon reception of signals, estimated from the transform samples at these various central sections. The reconstructed picture is produced by the two-dimensional inverse Fourier transform.
