How we measure 'reads'
A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text. Learn more

The inpainting method implemented in this work was used to estimate the missing information in a range image from a single image, achieved independence of the RGB image of the scene or multiple range images to perform the restoration. The proposal is based on improving the results of restoring range images using the Gaussian Pyramid method. This, f...

In mammograms, a calcification is represented as small but brilliant white region of the digital image. Earlier detection of malignant calcifications in patients provides high expectation of surviving to this disease. Nevertheless, white regions are difficult to see by visual inspection because a mammogram is a gray-scale image of the breast. To he...
This proposal presents the object detection using Sparse Keypoint Detector technique, in which is computed the interesting points from directional surface. This surface is built with the normal vectors corresponding to the homogeneous surface, and this in turn, is obtained from range image. A probability dense function (pdf) analysis applied to the...

The object surfaces on the Range images can be easily treated as elevations, at each point of these surfaces. The Sparse Normal Detector technique focuses in the extraction of keypoints, from homogeneous surface of Range images. Additionally, the contour of the objects in the scene can be represented through these points. First, the homogeneity fea...
