High compression ratio image compression

1993 IEEE International Symposium on Circuits and Systems, 2002
An image compression method is proposed. It makes use of the wavelet transform (WT) with better frequency localization and the adaptive hierarchical vector quantization (AHVQ) technique. The WT provides a multifrequency channel representation for the image from which proper coding methods can be drawn.

Compression ratio boundaries for predictive signal compression

IEEE Transactions on Image Processing, 2001
Predictive regressional models like DPCM are widely used in digital signal compression. This paper analyzes the relationship that exists between the predictive model fitness and the resultant reduction of the first-order signal entropy, and finds the lossless compression ratio C as a function of predictive model correlation rho.

Improving Compression Ratio in CASSI

OSA Imaging and Applied Optics Congress 2021 (3D, COSI, DH, ISA, pcAOP), 2021
We propose a new approach to improve the compression ratio in CASSI while maintaining the simplicity of the system and single-snapshot acquisition. We evaluate simulations of the modified method, which confirm the reconstruction quality improvement.
