Resolution enhancement of ultrasonic B-mode images

COMPUTER SIMULATION OF ULTRASONIC SCATTERING AND TEXTURE IN B-MODE IMAGES JiminZhang Echo Ultrasound Reedsville,

Diagnostic ultrasound has been widely used in clinical applications, such as soft tissue abnormality detection and blood flow detection. However, due to the complexity of ultrasonic wave propagation and scattering in biological tissues which generally involves wave reflection, refraction, scattering, absorption and other wave phenomena, it has always been a rather difficult task to interpret th...

Learning Based Resolution Enhancement of Iris Images

Iris recognition is one of the most reliable personal identification methods. The potential requirement of obtaining high accuracy is that users supply iris images with good quality. It is thus necessary for an iris recognition system to operate the possibly blurred iris images due to less cooperation of users and camera with low resolution. This paper proposes a new algorithm for resolution en...

Multi Resolution Fuzzy Segmentation of Satellite Images

Super-resolution of Defocus Blurred Images

Super-resolution is a process that combines information from some low-resolution images in order to produce an image with higher resolution. In most of the previous related work, the blurriness that is associated with low resolution images is assumed to be due to the integral effect of the acquisition device’s image sensor. However, in practice there are other sources of blurriness as well, inc...

Temporal Resolution Enhancement for AMSR Images

Some techniques which average multiple AMSR satellite data passes into daily sets create images with diminished temporal resolution. This results from averaging data of multiple overlapping passes separated by many hours. Overlap can be reduced by instead grouping data according to local time of day. This new method maximizes temporal resolution by decreasing both the number and the temporal va...
