Streaming medical images using video compression
2016 IEEE Symposium on Computers and Communication (ISCC), 2016In 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.

Compressive video sensors using multichannel imagers
Applied Optics, 2010We explore the possibilities of obtaining compression in video through modified sampling strategies using multichannel imaging systems. The redundancies in video streams are exploited through compressive sampling schemes to achieve low power and low complexity video sensors.

Image/video spatial scalability in compressed domain
IEEE Transactions on Industrial Electronics, 1998Image/video compression is widely used in various applications with the advent of the Joint Photographic Expert Group (JPEG), Motion Picture Expert Group (MPEG), and H.261 standards. Hence, most visual data are stored in the compressed format. Spatial scalable encoding of visual data has several applications, including browsing visual databases ...

Toward Compression of Encrypted Images and Video Sequences
IEEE Transactions on Information Forensics and Security, 2008We present a framework for compressing encrypted media, such as images and videos. Encryption masks the source, rendering traditional compression algorithms ineffective. By conceiving of the problem as one of distributed source coding, it has been shown in prior work that encrypted data are as compressible as unencrypted data.

Perceptual cryptography on JPEG2000 compressed images or videos
The Fourth International Conference onComputer and Information Technology, 2004. CIT '04., 2004In this paper, a perceptual cryptography combining with JPEG2000 codec is proposed, which permutes different number of bit-planes in each code block, encrypts different number of coefficients' signs, and permutes code blocks in different frequency bands. Thus, the images or videos can be degraded to different degrees under the control of quality factor.

From image and video compression to computer graphics
Proceedings 2000 International Conference on Image Processing (Cat. No.00CH37101), 2000We report previous effort in expanding image and video compression to computer graphics applications, in particular those based on image-based rendering. We then introduce our progress in developing a networked immersive environment that integrates image analysis, face animation, and streaming of 3D objects, to provide a truly immersive environment ...

Optimal Image Tilings with Application to Video Compression
2006 International Conference on Image Processing, 2006We build on our previous work on best basis selection algorithms in large tree-structured dictionaries, previously used to construct effective image coders based on block and lapped transforms. In the present paper, we use such algorithms to select the optimal tiling for the motion compensation step in video compression. We illustrate the effectiveness

Scalable Image and Video Compression
2018This 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 ...

Image/Video Compression with Artificial Neural Networks
2009Both Information Compression and Parallel Processing are key issues nowadays. And both are our framework for our proposal. Our purpose was to accomplish an exhaustive study about patterns recognition using backpropagation neural networks with multilayer perceptron topology for its subsequent application to image and video compression.

Digital Image and Video Compression
2011For a long time, data compression was primarily intended to counteract the bandwidth limitations faced by computing equipment when handling internal and external data transfer and storage. Improvements in network and storage technology have gradually reduced these bandwidth limitations. Unfortunately, data volumes have continued to increase at the same
