We present tensor scale descriptor (TSD) - a shape descriptor for content-based image retrieval, registration, and analysis. TSD exploits the notion of local structure thickness, orientation, and anisotropy as represe...

Tracking moving objects in video sequence is an important problem in computer vision, with applications several fields, such as video surveillance and target tracking. Most techniques reported in the literature use ba...

Maximum entropy (MENT) is a well-known image reconstruction algorithm. If only a small amount of acquisition data is available, this algorithm converges to a noisy and blurry image. We propose an improvement to this a...

this paper presents a new method for segmentation and recognition of image objects based on structural pattern recognition. the input image is decomposed into regions through a quadtree algorithm. the decomposed image...

We present in this work a new method for the tomographic reconstruction with Poisson noise corrupted projections. the reconstruction method is a hybrid estimation theoretic-POCS (Projection Onto Convex Sets) method pe...

We present a sketching interface for modeling shapes defined by large sets of points. Our system supports powerful modeling operations that are applied directly to the points defining the surface. these operations are...

the notion of "strength of connectedness" between pixels has been successfully used in image segmentation. We present an extension to these works, which can considerably increase the efficiency of object def...

Patch-based texture synthesis builds a texture by joining together blocks of pixels - patches - of the original sample. Usually the best patches are selected among all possible using a L2 norm on the RGB or grayscale ...

We present a new method for computing the dimensions of boxes from single perspective projection images in real time. Given a picture of a box, acquired with a camera whose intrinsic parameters are known, the dimensio...

Oriented feature detectors are fundamental tools in image understanding, as many images display relevant information in the form of oriented features. Several oriented feature detectors have been developed;some of the...
