【Matlab】新学知识及问题解决


一、matlab 中函数“vision.x”的理解

MATLAB2012a及其更高版本中的Computer Vision System中的一大特点就是采用系统对象(System Object)进行编程,其提供了涉及视频显示、视频读写、特征检测、提取与匹配、目标检测、运动分析与跟踪、分析与增强、图像转换、滤波、几何变换、数学形态学操作、统计、添加文字和绘图、图像变换等方面。
采用系统对象进行编程的主要步骤包括:
1.        创建系统对象;
2.        修改系统对象属性;
3.        运行系统对象

vision函数的matlab帮助(2021a)

Computer Vision Toolbox? provides algorithms, functions, and apps for designing and testing computer vision, 3D vision, and video processing systems. You can perform object detection and tracking, as well as feature detection, extraction, and matching. You can automate calibration workflows for single, stereo, and fisheye cameras. For 3D vision, the toolbox supports visual and point cloud SLAM, stereo vision, structure from motion, and point cloud processing. Computer vision apps automate ground truth labeling and camera calibration workflows.

You can train custom object detectors using deep learning and machine learning algorithms such as YOLO v2, SSD, and ACF. For semantic and instance segmentation, you can use deep learning algorithms such as U-Net and Mask R-CNN. The toolbox provides object detection and segmentation algorithms for analyzing images that are too large to fit into memory. Pretrained models let you detect faces, pedestrians, and other common objects.

You can accelerate your algorithms by running them on multicore processors and GPUs. Toolbox algorithms support C/C++ code generation for integrating with existing code, desktop prototyping, and embedded vision system deployment.
