During the last few decades, there has been a tremendous development in the field of biological sciences. With this, there is an increasing demand for analyzing the molecular or cellular features of the cell in the images, acquired with the electron microscopes (EM). However, despite significant progress in image processing, the efficient detection of(More)
This paper presents a study on edge marking scheme of various standard edge detectors viz. Sobel, Prewitt, Roberts, Laplacian of Gaussian (LoG) and Canny. On the basis of edge map obtained for a synthetic rectangular board image, obtained from five edge detectors, suggests classifying the detectors in three categories namely, pre-marker, post-marker and(More)
High-Level Synthesis (HLS) has become a very popular instrument to facilitate rapid development of production-ready implementations for FPGAs. Ever increasing flexibility of the frameworks, however, demands a very high level of domain-specific knowledge from the designer. Examples for such knowledge in window-based image processing are median computation(More)
The study proposes a novel image denoising algorithm based on Adaptive Weighted Quartic Order Bézier Approximation (AWQBA), for the images corrupted with low density saturated impulse noise, often termed as salt-and-pepper noise. The proposed algorithm first detects the presence of noisy pixel in sliding window of dimension 5×5, followed by(More)
The study proposes a novel image denoising algorithm based on the regression splines (RS) for the restoration of images corrupted with the Gaussian noise. In the proposed algorithm, overlapping window of dimension 5×5 have been considered to replace the central pixel value with the local minimum of both diagonal pixels and central row and column(More)
The paper proposes a shot boundary detection system using Gist and local descriptor. Gist provides the perceptual and conceptual information of a scene. The proposed system can be roughly divided into three steps. The first step consists of forming of groups of frames by calculating the correlation of the Gist features between consecutive frames of the(More)
