Coding algorithm for grayscale images based on Linear Prediction and dual mode quantization

作者：

Highlights：

• We propose a new method of grayscale image compression.

• The algorithm is based on a prediction technique.

• We use quantizers designed for discrete input samples.

• Proposed model provides higher PSQNR up to 6.14 dB in comparison to other similar models.
