Bilateral Exposure and Contrast Management System
Under the supervision of Professor Frédo Durand, I have designed and implemented a software system that provides users flexibility in controlling the exposure of selective areas of a high-dynamic-range image. When the user selects an area of the image to modify, the system renders an alpha channel using a non-linear bilateral algorithm. This algorithm takes into account both spatial information...
متن کاملFuzzy Inference System based Contrast Enhancement
In this work, we propose a fuzzy inference system based contrast enhancement of gray level images. We propose a new method of generating the fuzzy if-then rules specific to a given image based on the local information available to be used by a fuzzy inference system. To this end, we only generate a partial histogram and not a complete histogram thus saving on computational costs. We also give a...
متن کاملContrast Sensitivity of the Motion System
A number of experiments were conducted to investigate how global-motion performance varies with luminance contrast. When all the dots in the stimulus were the same contrast, performance improved with increasing contrast up to about the 15% level (Experiment 1). Increasing the contrast beyond this level had no additional effect on performance. When the contrast of a subgroup of the dots was vari...
متن کاملA Nanocomplex System as Targeted Contrast Agent Delivery Vehicle for MRI Dynamic Contrast Enhancement Study
We have developed and tested a liposomal nanocomplex system, which contains Gd-DTPA as a payload and transferrin on the surface, as a tumor specific targeting MRI contrast agent for studying prostate cancer tumors in mice. In vivo, the probe significantly enhanced the MRI signal. The image contrast between the peripheral region of the tumor and the non-involved muscle was nearly 50% higher two ...
متن کاملEffects of contrast media on the hepato-pancreato-biliary system.
AIM To determine the effects of high osmolarity contrast media (HOCM) and iso-osmolar contrast media (CM) application, with or without pressure, on hepato-pancreato-biliary (HPB) system. METHODS Sixty rats were divided into six equal groups as follows: Group 1: (0.9% NaCl, control), Group 2: (diatrizoate meglumine Na, ionic HOCM, Urographin), Group 3: (iodixanol, iso-osmolar non-ionic CM, Vis...
