In this paper, we propose a novel variational method for color image segmentation using modified geodesic active contour method. Our goal is to detect Object(s) of Interest (OOI) from a given color image, regardless of other objects. The main novelty of our method is that we modify the stopping function in the functional of usual geodesic active contour(More)
In this paper, we propose a two-stage method for denoising images heavily contaminated by salt and pepper noise. In the first stage, we use adaptive median filter to detect the noisy pixels. All the pixels are marked as noisy or noisefree pixels. In the second stage, we take the noisy pixels as inpainting regions and noise-free pixels as true information.(More)
In this paper, we present a novel behavior frequency domain modeling in application to modern communication systems to describe the third order inter-modulation distortions and harmonic distortions in high frequency signal processing environments based on Volterra series. By using model order reduction techniques, we are able to speed up the simulation(More)
