computer vision 里有个著名的 SIFT algorithm. 具体这个算法 bro 就不赘述了. it's such a telling example of showing off what computers are good at, how it differs from humans, and how it accomplishes superhuman performance. a
This is one of the most exciting aspects of working in computer vision! SIFT computer vision, or Scale Invariant Feature Transform, is a feature detection algorithm in Computer Vision. SIFT algorithm helps locate the local features in an image, commonly known as the ‘keypoints‘ of the image...
Compared with the original SIFT algorithm, the proposed algorithm reduced the computational amount by 90 % and memory usage by 95 %. The final implementation used 58K gate count for UMC 90-nm CMOS technology, and offered 6000 feature points per frame for VGA size image at 30 frames per ...

Computer Vision_33_SIFT:An efficient SIFT-based mode-seeking algorithm for sub-pixel registration of remotely sensed images——2015 此部分是计算机视觉部分,主要侧重在底层特征提取,视频分析,跟踪,目标检测和识别方面等方面。对于自己不太熟悉的领域比如摄像机标定和立体视觉,仅仅列出上google上引用次数比较多的...
Therefore, it is of great significance to study the registration of optical and SAR images in image processing and analysis, image fusion, computer vision and other fields3. Registration algorithms can be divided into gray based registration algorithm and feature-based registration algorithm. The ...
The Scale Invariant Feature Transform (SIFT) algorithm is widely used in computer vision to match features between images or to localize and recognize objets. However, mostly because of speckle noise, it does not perform well on synthetic aperture radar (SAR) images. We present here an improvemen...
