IMAGE AND VIDEO COMPRESSION: A REVIEW

International Journal of High Speed Electronics and Systems, 1997
The area of image and video compression has made tremendous progress over the last several decades. The successes in image compression are due to advances and better understanding of waveform coding methods which take advantage of the signal statistics, perceptual methods which take advantage of psychovisual properties of the human visual system (HVS)

Multi-Plane Image Video Compression

2020 IEEE 22nd International Workshop on Multimedia Signal Processing (MMSP), 2020
Multiplane Images (MPI) is a new approach for storing volumetric content. MPI represents a 3D scene within a view frustum with typically 32 planes of texture and transparency information per camera. MPI literature to date has been focused on still images but applying MPI to video will require substantial compression in order to be viable for real world

Temporal compressive imaging for video

2017 International Conference on Optical Instruments and Technology: Optoelectronic Imaging/Spectroscopy and Signal Processing Technology, 2018
In many situations, imagers are required to have higher imaging speed, such as gunpowder blasting analysis and observing high-speed biology phenomena. However, measuring high-speed video is a challenge to camera design, especially, in infrared spectrum.

Feature-preserving image/video compression

SPIE Proceedings, 2005
Advances in digital image processing, the advents of multimedia computing, and the availability of affordable high quality digital cameras have led to increased demand for digital images/videos. There has been a fast growth in the number of information systems that benefit from digital imaging techniques and present many tough challenges. In this paper

Near-infrared temporal compressive imaging for video

Optics Letters, 2019
Without decreasing spatial resolution, temporal compressive imaging (TCI) can improve the temporal resolution of an imaging sensor and relax the requirement of the data readout speed in high-speed imaging. In this Letter, we describe a near-infrared TCI system that can reconstruct 500 fps videos from coded measurement frames sampled at 50 fps.

Image and video compression for HDR content

SPIE Proceedings, 2012
High Dynamic Range (HDR) technology can offer high levels of immersion with a dynamic range meeting and exceeding that of the Human Visual System (HVS). A primary drawback with HDR images and video is that memory and bandwidth requirements are significantly higher than for conventional images and video.

Video Post-Production with Compressed Images

SMPTE Journal, 1994
This article presents new methods for performing two video post-production practices directly on subband compressed images, i.e., without decoding them first. The first post-production operation is composition of two images, i.e., realizing picture-in-picture.

Streaming medical images using video compression

2016 IEEE Symposium on Computers and Communication (ISCC), 2016
In the last few years, the need for transferring all storage, process units, and memory to the cloud increased for many reasons as for cost reduction & staff productivity optimization. In the medical field,the cloud-based technology can eliminate the need for CDs and the streamline of the image management process.

CMOS image sensors with video compression

Proceedings of 1998 Asia and South Pacific Design Automation Conference, 2002
This paper describes CMOS image sensors integrating video compression circuits. The on-sensor compression is particularly useful for the low-power design of moving picture compression hardware, which is demanded especially in the mobile computing and telephony.

Scalable Image and Video Compression

2018
This chapter introduces the fundamental concepts employed in (scalable) image and video compression schemes, which are required to understand and appreciate the contributions of this thesis. The main difference between image and video compression is that the latter can exploit both spatial and temporal redundancies in the data, which results in higher ...
