Medical Image Compression And Reconstruction Using Compressive Sensing (original) (raw)

2015, Journal of emerging technologies and innovative research

Compressive sensing is new era and emerging platform for data acquisition and signal processing. Magical statement of Compressive sensing tells that one can recover certain signal or images from far fewer samples than traditionally required. Image Compression, the art and science of reducing the amount of data required tore present image is one of the most useful and commercially successful in the field of digital image processing. Image compression plays important role in many other areas, including tele video conferencing, remote sensing, document and medical imaging, and facsimile transmission. On encoding side it require two property of a signal that are sparsity and incoherence. First, any signal is converted into particular transform i.e. wavelet or DCT, with help of sensing matrix it extracts required coefficients which has less dimensionality than image dimensions and hence we can get resultant matrix. which is also called measurements which are non-adaptive. In certain area...
