To evaluate the safety and efficacy of transarterial chemoembolization and to identify the prognostic factors associated with survival in patients with hepatocellular carcinoma (HCC) and portal vein (PV) invasion.From January 2006 to March 2012, 50 patients with HCC invading into the PV (Barcelona Clinic Liver Cancer stage C) were treated with transarterial chemoembolization. The parenchymal tumor...
With the improvement in technology of thin-film-transistor liquid-crystal display (TFT-LCD), the resolution requirement of display becomes higher and higher. Super-resolution algorithms are used to enlarge original low-resolution (LR) images to meet the visual quality of the high-resolution (HR) display. In this research, an efficient super resolution algorithm is proposed. The proposed algorithm...
Due to the development of multimedia hardware and computer devices, single-image super resolution has recently become a hot topic. The main concept of super resolution is to obtain a high-resolution image from a low-resolution one, and the former should look like it had been acquired with a sensor having the resolution of the up scaled image or, at least, present a ¡¨natural¡¨ texture. Most existing...
Satellite images have been more and more popularly used in our daily life. For satellite image compression, the Consultative Committee for Space Data Systems (CCSDS) had proposed an image compression standard (CCSDS-ICS) which is so far the most widely implemented in hardware. CCSDS-ICS provides good compression performance under the measure of PSNR. However, PSNR is a concept of average differences...
In the modern compression system, besides high compression qualities and low bit rates, others extra functional capabilities become more and more important. For the use of satellite images, the data size is always very large and the users might be just interested in some regions of a satellite image. Thus it is an ideal way to keep the better quality in the regions of interest than in others in a...
