HTML5 SVG 2D entry 6-Windows coordinate system and user coordinate system and transformation Overview

belongs to the elements for creating windows. After the Windows coordinate system is determined, the coordinate tone of the entire window is determined. However, the user coordinate system belongs to each Graphic Element. As long as the coordinate transformation is performed on the image, a new user coordinate system is created. All coordinates and dimensions of the element use the new user coordinate system. Simply put: The Window coordinate system

I. K-L transformation If you say PCA, you must first introduce the K-L transformation. The K-L transformation is the abbreviation of Karhunen-loeve transformation and is a special orthogonal transformation. It is based on statistical characteristics of a

Discrete cosine transformation (including source code)

In addition to Fourier transformation, commonly used orthogonal transformations in image processing also have some useful orthogonal transformations. The Discrete Cosine is one of them. Discrete cosine transform is represented as DCT (discrete cosine transformation), which is often used in image processing and image recognition.One-dimensional discrete cosine transforma

An Interpretation of the affine matrix transformation of Silverlight Rotation

The MatrixTransform attribute changes are required for the Silverlight rotation animation. This is a function of the affine matrix transformation, which allows the image to produce visual rotation. Its principle is not to change the position of an image, but to change the coordinate system of the plane x and y, indirectly changing the coordinates of the image, how to accurately control the image rotation by rotating the coordinate system is the role o
