Image processing by alternate dual Gabor frames

‎We present an application of the dual Gabor frames to image‎ ‎processing‎. ‎Our algorithm is based on finding some dual Gabor‎ ‎frame generators which reconstructs accurately the elements of the‎ ‎underlying Hilbert space‎. ‎The advantages of these duals‎ ‎constructed by a polynomial of Gabor frame generators are compared‎ ‎with their canonical dual‎.

automated detection of inner surface defects in pipes using image processing algorithms

this paper presents a new methodology for the automated inspection of pipes. standard inspection systems are based on closed-circuit television cameras which are mounted on remotely controlled robots and connected to remote video recording devices. the main problems of such camera-based inspection systems are: 1) the lack of visibility in the interior of the pipes and 2) the poor quality of the...

Image Enhancement of Coronary Angiograms by Nonlinear Filtering

Nonlinear lters based on order statistics have excellent properties in the presence of noise. They tend to preserve the edge information which is very important in detecting the boundaries of the arteries. Current algorithms apply linear lowpass ltering prior to the detection of the boundaries so as to reduce the effect of imaging noise. However, this procedure tends to smear the edges and decr...
