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. When the processor 80 executes the computer program 82 Realize the steps in each embodiment as described in embodiment 1, for example figure 1 Step S101 to step S105 are shown. Alternatively, when the processor 80 executes the computer program 82, it realizes the functions of each module in each device embodiment as described in Embodiment 2, for example Figure 5 The functions of modules 110 to 150 are shown.
[0117] The terminal device 8 may be computing devices such as desktop computers, notebooks, palmtop computers, and cloud servers. The terminal device 8 may include, but not limited to, a processor 80 and a memory 81 . For example, the terminal device may also include an input and output device, a network access device, a bus, and the like.
[0118] The so-called proc...
