Embodiment Construction

[0035] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0036] A data block division method based on scale transformation of the present invention, such as figure 1 shown, follow the steps below:

[0037] Step 1. Draw a data curve, reduce the data curve proportionally, mark the middle position points of the vertical coordinates of multiple pixel points corresponding to the same abscissa on the data curve, and connect the middle position points in turn to obtain a smooth data curve;

[0038] Step 1.1, draw data X=[x 1 ,x 2 ,...,x n ] graph, such as figure 2 shown, where n represents the number of data points, remove the border of the graph and all annotations, and save it as a picture format;

[0039] Step 1.2, record the image size of the curve obtained in step 1.1 as k 1 *k 2 ,like image 3 shown, and then reduce the size of the image to the original size And save it as figure1.jpg, reme...

Abstract

The invention discloses a data block division method based on scale transformation, which divides the data into blocks according to the overall idea of ​​big data processing, and then divides the data based on the scale transformation method, and then can analyze the data trend on this basis , which solves the problem that the data is difficult to divide when the amount of data is large and too much attention is paid to the detailed data points; the invention also has the advantages of simple operation, accurate and fast division results.

Description

technical field [0001] The invention belongs to the technical field of data processing methods, and in particular relates to a method for dividing data blocks based on scale transformation. Background technique [0002] With the development of big data, the field of data processing technology is also developing continuously. How to better divide data blocks when the amount of data is too large has become a major problem to be solved. When the amount of data is too large, if the data curve is enlarged to a certain size, it will increase the difficulty of data division due to too much attention to detail data; and if the image size is continuously reduced, the distribution of points on the curve will be very dense, so that It is easier to see the general trend of the curve, and it is more conducive to the computer to divide the data blocks quickly and accurately. The data blocks can be divided based on the overall idea. Therefore, for this problem, a method based on scale tran...
