Selection of feature points
In visual tracking, the selection of feature points is very important. Different feature point selection methods will affect the tracking effect. Therefore, it is necessary to select appropriate feature points according to specific application scenarios and requirements.
Optical flow method
Optical flow method is an operation method based on time statistical characteristics, which is used to calculate the motion of objects in image sequences. It can track the object by calculating the pixel displacement between adjacent frames.
Characteristic optical flow method
Characteristic optical flow method is an optical flow method based on feature points, which realizes target tracking by selecting representative feature points. Different from the optical flow method, the characteristic optical flow method can handle the rotation and scaling of objects better.
Learning material recommendation
For beginners, I recommend reading the book Digital Image Processing by Gonzalez, which is easy to understand and very suitable for beginners. At the same time, it is suggested to study the books related to image processing in depth to help us understand these concepts and methods more comprehensively.
Suggestions on writing master's thesis
Before writing a master's thesis, we need to spend more time in-depth understanding of relevant theoretical knowledge and practical methods. At the same time, the paper should clearly describe the methods used, the experimental process and the results, so that readers can better understand the research content and results.
