OpenCV shape matching between two similar shapes
WebbShape is represented in an implicit form and it is characterized by a series of isotropic kernels that provide desirable invariance properties. The shape features are characterized at multiple scales which form a signature that is a compact description of shape over a range of scales. The key of shape based matching, or linemod, is using gradient orientation only. Though both edge and orientation are resistant to disturbance,edge have only 1bit info(there is an edge or not), so it's hard to dig wanted shapes out if there are too many edges, but we have to have as many edges as possible if we … Visa mer Well, issues are not clearly classified and many questions are discussed in one issue sometimes. For better reference, some typical … Visa mer Comparing to opencv linemod src, we improve from 6 aspects: 1. delete depth modality so we don't need virtual func, this may speed up 2. … Visa mer orchid casting

Webb28 okt. 2024 · Shape-Based matching的基本流程 HALCON提供的基于形状匹配的算法主要是针对感兴趣的小区域来建立模板，对整个图像建立模板也可以，但这样除非是对象在整个图像中所占比例很大，比如像视频会议中人体上半身这样的图像，我在后面的视频对象跟踪实验中就是针对整个图像的，这往往也是要牺牲匹配速度的，这个后面再讲。 基本流程 … WebbThis paper proposes a method for obtaining surface normal orientation and 3-D shape of plano-convex lens using refraction stereo. We show that two viewpoints are sufficient to solve this problem under the condition that the refractive index of the object is known. What we need to know is that (1) an accurate function that maps each pixel to the … Webb16K views 6 years ago HALCON and MERLIC Tutorials Shape-based matching can be used for many different machine vision applications.
