On the Internet to see an article, looked after the feeling quite deep. He tells the nature of linear algebra, and intuitively describes linear spaces, vectors, and matrices. The linear algebra course, whether you start from the determinant or

1, the structure of OpenCV Like Python, the current OPENCV also has two large versions, OpenCV2 and OpenCV3. Compared to OPENCV2,OPENCV3 provides more features and more convenience features. However, considering the compatibility with the depth

Coordinate System in Windows GDI (2) By leezy_2000   1. How is the coordinate of the Logical space converted into the coordinate of the device space?   Let's clarify how the logical coordinate space is converted.   The transformation

OpenCV is one of the most widely used open source visual libraries. He allows you to use very little code to detect a person's face in a picture or video. Here are some tutorials on the internet to illustrate how to use affine transformations

Then understand the matrix. "The matrix is the description of the motion", and so far, it seems that no one has any opinion about it. But I believe that sooner or later there will be friends from the mathematics department to make the decision.

Today, I was suddenly asked, What is the matrix used? What is the significance of its feature root. The answer is far-fetched. Later, I searched for a lot of things on the internet and thought it was good to share them. The Matrix is a description

The classical literature of feature detection and tracking is the article of Shi and Tomasi 1994 (see Reference), although it is very classical. In this paper, a feature extraction method, a tracking algorithm based on image affine transformation

Not long ago, for some ulterior motives, chensh wanted to act as a teacher and teach others linear algebra. As a result, I was held down and discussed with him several times about the virtual nature of linear algebra. Obviously, it is difficult for

In almost any graphics system, conversion is the most important function, but it is not actually involved in drawing. The purpose of the transformation is to modify the coordinates by using mathematical formulas (usually expressed as matrix

The concept of homogeneous coordinates has not been fully understood, most of the book said that "homogeneous coordinates in the affine transformation is very convenient", then there is no later text, today in a blog called "300 Years of rebirth,"
