DIGITAL VIDEO BANDWIDTH COMPRESSION SYSTEMS EMPLOYING BLOCK TRUNCATION CODING
Abstract
A technique for bandwidth compression coding of sequential digitized video imagery is presented. The method uses adaptive one bit quantization over small blocks of space and time. The system includes global registration and motion detection for optimal bit assignments. A comparison is made with a conditional replenishment technique using a motion compensated predictor described in the literature. The method presented produces reconstructed video sequences filmed from low altitude aircraft with negligible degradation at 0.9 bit per pixel data rate. Robust behavior in the presence of channel noise is demonstrated.
