Digital image processingparallel computingCUDAIJCSIThis paper presents an approach the point to point processing of digital images using parallel computing, particularly for grayscale, brightening, darkening, thresholding and contrast change. The point to point technique applies a transformation to each ...
Points (r1, s1) and (r2, s2) control the shape of the transformation. The selection of control points depends upon the types of image and varies from one image to another image. If r1 = s1 and r2 = s2 then the transformation is linear and this doesn’t affect the image. In other ...
The transformer block集成了the self-attention layer, linear projections(reduce dimensionality and accelerate processing),a residual connection。输入是一组具有3D坐标 p 的特征向量 x。The point transformer block有助于这些局部特征向量之间的信息交换,为所有数据点生成新的特征向量作为其输出。信息聚合适应于特征向...

Whatisimageenhancement?采用一系列技术去改善图象的视觉效果，或将图象转换成一种更适合于人或机器进行分析处理的形式。图象增强不以图象保真为准则，而是有选择地突出某些对人或机器分析有意义的信息，抑制无用信息，提高图象的使用价值。Example:Example: Whatisagoodimage?For Acertainamountoftrial(试)anderror...
A method of automatic indication recognition for a point meter by image processing is presented. The principle and step of the automatic indication recognition meter are described. Image analysis and recognition algorithms, such as threshold iterative gray level transformation and Hough transformation, edg...
In many applications of computer vision, the following problem is encountered. Two point patterns (sets of points) (x/sub i/) and (x/sub i/); i=1, 2, . . ., n are given in m-dimensional space, and the similarity transformation parameters (rotation, translation, and scaling) that gi...

and it is independent of the world coordinate system. Based on the unique LRF construction, the descriptor invariably performs a rigid transformation and has high descriptiveness because it preserves abundant spatial information of the local surface. Compared to quantitative descriptors without LRF, LRF...
