We propose to employ bilateral filters to solve the problem of edge detection. The proposed methodology presents an efficient and noise robust method for detecting edges. Classical bilateral filters smooth images without distorting edges. In this paper, we modify the bilateral filter to perform edge detection, which is the opposite of bilateral smoothing.(More)
We propose a method for ridge detection at different widths using second-order Gaussian derivative masks. The width of the ridge extracted varies depending on the mask size and its parameter, σ. In the proposed method, the ridge orientations are estimated as an initial step by finding the zerocrossings of the first derivative of the second(More)
In content-based image retrieval systems, visual content of the image is the criterion for measuring image similarity. We propose a method to solve the problem of loss of spatial information of objects when local descriptors from an image with multiple objects are aggregated to form a global representation. In our approach, after saliency-based spatial(More)
