Computer analysis of high-speed videoendoscopy (HSV) recordings is becoming increasingly useful in functional evaluation of vocal fold pathology. In this work we present two new approaches for the vocal fold HSV-based analysis that have not been previously reported. First, segmentation of vocal fold edges is performed in our method using the level set algorithm. Second, having two vocal fold contours...
Recently, medical imaging has increased its importance greatly in picture archiving & communication (PACS). Many current compression schemes provide a very high compression rate but with considerable loss of quality. On the other hand, in some areas of image processing, in particular medical images, it may be sufficient to maintain high image quality only in the region of interest, i.e., in diagnostically...
Super-Resolution algorithms are typically formulated as optimization problems with significant computational burden which disables real-time applications. We propose a computationally simple SR algorithm for increasing spatial resolution of images. The algorithm was designed for autonomous endoscopic capsule with objective of real time application. The significant computational speed-up was achieved...
This paper presents the 32times32 CMOS VLSI chip of synchronised oscillators network designed for fast segmentation and labeling of binary images. The network chip architecture and its functional blocs were briefly described. The hardware realisation of oscillator network provides much faster image segmentation when compared to computer simulation techniques. Segmentation results of sample biomedical...
