Embodiment 1

[0033] figure 1 It shows the implementation flow of a region extraction method provided by an embodiment of the present invention, and the process is described in detail as follows:

[0034] In step S101, an initial contour point set is read.

[0035] In this embodiment, firstly, an initial contour point set of arbitrary shape is obtained in a designated area.

[0036] In this embodiment, the specific methods for obtaining the initial contour point set in the program include:

[0037] First read the initial contour point set in the xml (Extensive Markup Language, extensible markup voice) file, the coordinates of the initial contour point set arranged in a preset order are recorded in the xml file, and the preset order can be a clockwise order , or in counterclockwise order. When the coordinates of the initial contour point set are obtained, in order to facilitate the operation of the program, the coordinates of the first contour point of the initial contour point set are in...

Embodiment 2

[0089] Such as Figure 5 As shown, an embodiment of the present invention provides an area extraction system 100 for performing figure 1 The method step in the corresponding embodiment, it comprises:

[0090] The initial contour point set reading module 110 is used to read the initial contour point set;

[0091] A single-pixel contour acquisition module 120, configured to sequentially fill and refine the rectangular area between two adjacent contour points in the initial contour point set to obtain a single-pixel contour;

[0092] A target area acquisition module 130, configured to acquire the target area surrounded by the single-pixel contour line;

[0093] A rectangular region of interest acquisition module 140, configured to acquire a rectangular region of interest according to the target region;

[0094] The target ROI 150 is configured to determine whether the rectangular ROI is a target ROI.

[0095] As can be seen from the foregoing embodiments, by reading the initi...

Embodiment 3

[0116] The embodiment of the present invention also provides a terminal device 8, including a memory 81, a processor 80, and a computer program 82 stored in the memory 81 and operable on the processor.

Abstract

The invention is applicable to the technical field of pattern recognition, and provides an area extraction method, system and terminal device, comprising: reading an initial contour point set; Filling and thinning processing are performed to obtain single-pixel contour lines; a target area surrounded by single-pixel contour lines is obtained; a rectangular area of ​​interest is obtained according to the target area; and whether the rectangular area of ​​interest is the target area of ​​interest is determined. In this embodiment, single-pixel contour lines are obtained by filling and thinning processing, which overcomes the shortcoming of easy deformation and fracture; and this embodiment only needs to scan the image once when judging whether the rectangular area of ​​interest is the target area of ​​interest, avoiding repeated traversal. The region extraction efficiency is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of pattern recognition, and in particular relates to an area extraction method, system and terminal equipment. Background technique [0002] In recent years, pattern recognition has been widely used in authentication, human-computer interaction and other fields, such as positive sample extraction of training set in deep learning, image segmentation, license plate recognition, etc. How to efficiently and correctly extract a rectangular ROI (Region Of Interest) within an arbitrary shape contour point set is a necessary condition for solving many pattern recognition problems. [0003] At present, morphological methods and mathematical methods are usually used to extract contour points of arbitrary shape areas. However, using mathematical methods to connect contour points does not effectively utilize the morphological information of the contour in the image. The contour is easily deformed and it is difficult to ...
