File compression is the process of reducing the size of a file while preserving its content. This is typically used to save storage space, reduce transfer time over the internet, and enhance system ...
We build a state model of the DC coefficients of the entire image. On each 8x8 block in the image, we perform DCT, quantization, and run length encoding on the resulting coefficients. Normally ...
ABSTRACT: Data compression plays a key role in optimizing the use of memory storage space and also reducing latency in data transmission. In this paper, we are interested in lossless compression ...
One student’s desire to get out of a final exam led to the ubiquitous algorithm that shrinks data without sacrificing information. With more than 9 billion gigabytes of information traveling the ...
Abstract: Image privacy protection and management face many challenges, such as privacy disclosure, copyright dispute, and traceability difficulties, with the development of big data. Reversible data ...
We consider the attributes of a point cloud as samples of a vector-valued volumetric function at discrete positions. To compress the attributes given the positions, we compress the parameters of the ...
