Rotation-invariant and scale-invariant Gabor features for texture image retrieval
Conventional Gabor representation and its extracted features often yield a fairly poor performance in retrieving the rotated and scaled versions of the texture image under query. ...

A Linear-Time Approach for Image Segmentation Using Graph-Cut Measures
Abstract. Image segmentation using graph cuts have become very popular in the last years. These methods are computationally expensive, even with hard constraints (seed pixels). We ...

Visual navigation with a time-independent varying reference
— In this paper, we present a controller for visual navigation, which utilizes a time-independent varying reference in the feedback law. The navigation framework relies on a mono...
