In this paper we use line segments from a Hough transform algorithm to locate vanishing points in an image. The line parameters have already been determined to high accuracy, and the purpose of this paper is to present a scheme for locating the vanishing points from the line intersections which takes full advantage of this accuracy. We present a natural generalisation of the usual accumulator m...

In this paper, we show that in a multi-camera context, we can effectively handle occlusions at each time frame independently, even when the only available data comes from the binary output of a fairly primitive motion detector. We start from occupancy probability estimates in a top view and rely on a generative model to yield probability images to be compared with the actual input images. We th...

Salient edge detection which is mentioned less frequently than salient point detection is another important cue for subsequent processing in computer vision. How to find the salient edges in natural images is not an easy work. This paper proposes a simple method for salient edge detection which preserves the edges with more salient points on the boundaries and cancels the less salient ones or n...

Synchronous generators are of two type’s salient pole type and round rotor type. The load angle curve of a cylindrical rotor synchronous machine comprises a single sine term only while in salient pole synchronous generators, power-angle characteristic has two terms. The first term is the fundamental component due to field excitation (the same as the cylindrical rotor) and the second term ...

Abstract In order to address estimation of mobile robot navigation, image sensors need acquire environmental information. This paper proposes sequence image match based on salient point invariants moments. It identifies salient point with SIFT scale-invariant algorithm, and the salient points have scale-invariant properties; it computes invariants moments of salient point neighborhood, search f...

The goal of this work is to evaluate 3D keypoints detectors and descriptors, which could be used for quasi real time 3D object recognition. The work presented has three main objectives: extracting descriptors from real depth images, obtaining an accurate degree of invariance and robustness to scale and viewpoints, and maintaining the computation time as low as possible. Using a 3D time-of-fligh...

A number of authors have enriched Nash’s original bargaining problem through the introduction of an additional point, which we call a salient point. When the salient point is restricted to lie in the bargaining set, it is interpreted as a reference point, the outcome, perhaps, of a bargain from an earlier period. When restricted to lie outside the bargaining set, it is interpreted as a claim on...

We image a rat cerebral cortex in situ by using a ring-based ultrasonic virtual point detector developed previously. Compared to the image generated by a finite-aperture detector, the image generated by the virtual point detector has a uniformly distributed resolution throughout the imaged area, owing to the lack of aperture effect of the ultrasonic detector. At the periphery of the image, the ...
