Abstract

The invention relates to a high-efficiency image collection and compression method. The method includes: adopting an image detector array to acquire a quantized digital image; utilizing a lower sampling module to acquire thumbnail data of an original image; acquiring data of the original data after dimension reduction through a compression sensing module; sequentially outputting the thumbnail data and compression sensing dimension-reduction data through a compressed data output module according to a preset compression ratio to form code stream used for transmission or storage; after the compressed data are stored and transmitted, completing reconstruction of the original image through an image reconstruction module. By the high-efficiency image collection and compression method, complexity of conventional image compression is lowered effectively, and the defect that a reconstruction step is needed to realize image looking-back on the basis of conventional compression sensing data is overcome.

Description

technical field [0001] The invention relates to the field of digital image acquisition and processing, in particular to an efficient image acquisition and compression method. Background technique [0002] In order to solve the storage and transmission challenges that need to be faced when dealing with massive image data, we usually use compression technology. Compression technology achieves a refined expression of the original digital signal to reduce the limitation of the original data on storage space and transmission bandwidth. Compression techniques broadly fall into two categories: lossless compression and lossy compression. Lossless compression, as the name implies, is to use the refined expression after signal compression to recover the original digital signal without any distortion; lossy compression is to use the refined expression after signal compression to roughly restore the original signal. There is a certain error, but the error is within an acceptable range...
