Description: GPU Accelerating Speeded-Up Robust Features. Many computer vision tasks require interest point detection and description, such as real-time visual navigation. We present a GPU implementation of the recently proposed Speeded-Up Robust Feature extractor, currently the state of the art for this task. Robust feature descriptors can give vast improvements in the quality and speed of subsequent steps, but require intensive computation up front that is well-suited to inexpensive graphics hardware. We describe the algorithm’s translation to the GPU in detail, with several novel optimizations, including a new method of computing multi-dimensional parallel prefix sums. It operates at over 30 Hz at HD resolutions with thousands of features and in excess of 70 Hz at SD resolutions.

[DocumentsSegmentation

Description: Segmentation (image processing) From Wikipedia, the free encyclopedia Jump to: navigation, search In computer vision, segmentation refers to the process of partitioning a digital image into multiple segments (sets of pixels) (Also known as superpixels). The goal of segmentation is to simplify and/or change the representation of an image into something that is more meaningful and easier to analyze

Description: Our world is three-dimensional, but camera image is two-dimensional, in order to obtain the three-dimensional information of objective object’s by the two-dimensional images, we need to rebuild the three-dimensional model of the target so that we can target the quantitative analysis. The same subject in computer vision and photogrammetry community,the stereo vision-based three-dimensional reconstruction techniques have been widely used in medical imaging, robot navigation, virtual reality, terrain exploration and other fields.

Description: 一篇关于光流传感器的论文,光流传感器广泛应用于微型西轴飞行器的室内定位-Robust velocity and position estimation at high update rates is crucial for mobile robot navigation. In recent years optical flow sensors based on computer mouse hardware chips have been shown to perform well on micro air vehicles. Since they require more light than present in typical indoor and outdoor low-light conditions, their practical use is limited. We present an open source and open hardware design 1 of an optical flow sensor based on a machine vision CMOS image sensor for indoor and outdoor applications with very high light sensitivity. Optical flow is estimated on an ARM Cortex M4 microcontroller in real-time at 250 Hz update rate. Angular rate compensation with a gyroscope and distance scaling using a ultrasonic sensor are performed onboard. The system is designed for further extension and adaption and shown in-flight on a micro air vehicle.
