json transformation

This article mainly introduces the HTML5Canvas method for controlling the graphic matrix transformation, and focuses on the usage of using the transform () method to control CSS pixel coordinates, which is very powerful, for more information about how to transform a matrix, see before introducing matrix transformation transform. The above is the transformation

%. Surprisingly, this goal is fraught with challenges, with teams from around the world using a variety of different technologies. The ultimate winning team "Bellkor's pragmatic Chaos" uses the core algorithm based on SVD.SVD provides a very convenient matrix decomposition method, which can discover the interesting potential patterns in the data. In this article, we will provide an understanding of SVD geometry and some simple examples of applications.the geometrical meaning of linear

I. Conversion of JSON objects to JSON strings1.How the jquery plugin supports conversion :$.parsejson (JSONSTR); Jquery.parsejson (JSONSTR), you can convert a JSON string into a JSON object2. browser supported conversion Mode (FIREFOX,CHROME,OPERA,SAFARI,IE9,IE8) and other browsers:Json.stringify (obj) converts the

(2) Parallel projection"The projection of the sun's rays is a parallel projection."If you move the center of the perspective projection to Infinity, each projection line becomes a straight line that is parallel to each other , and this projection is called a parallel projection.Parallel projection can be divided into two categories according to the projection direction and the angle of the projection plane: forward projection and oblique projection1> Positive ProjectionAccording to the "angle" o

§ 6 plane Cartesian coordinate transformation ITranslation Coordinate Transformation Definition: If the Cartesian coordinate system {O; I, j} and {O '; I', j '} meet the conditions of I = I', j = J ′, then, the coordinate system {O; I ', j'} can be viewed as translated by {O; I, j}, which is called by the coordinate system {O; I, the transformation from j} to the

Double-layer nested json string (json object embedded json array) resolved to Map I wrote an article on the layer that introduced the conversion between json and map, but only involved a single json object or json array, the

Application of Two-dimensional Fourier Transform As mentioned above, there are two advantages of Fourier Transformation: the ability to obtain the frequency-domain characteristics of signals, and the ability to convert convolution into product operations. Therefore, the application of two-dimensional Fourier transformation is based on these two features. Application in Image Filtering First, let's take a lo

157 suggestions for writing high-quality code to improve C # programs [correct string operations, use default transformation methods, but do not treat forced conversions with as and is], Preface This document describes the first three suggestions. 1. Correct string operations Suggestion 2. Use the default Transformation Method Suggestion 3. differentiate between forced conversion and as and is There are a l

around the Z axis: Rotate around X axis: Rotate around the y axis: The rotation transformation of arbitrary axes around the specified three-dimensional space can be decomposed into the superposition of a rotation transformation and a translation transformation that are about three axes respectively.
