Embodiment 1
[0060] First, refer to figure 1 The processing device 100 for implementing the embodiments of the present invention will be described, and the processing device can be used to run the methods of the various embodiments of the present invention.
[0061] Such as figure 1 As shown, the processing device 100 includes one or more processors 102, one or more memories 104, an input device 106, an output device 108, and a data collector 110, and these components are connected through a bus system 112 and / or other forms ( not shown) interconnection. It should be noted that figure 1 The components and structure of the processing device 100 shown are only exemplary, not limiting, and the processing device may also have other components and structures as required.
[0062] The processor 102 may be implemented in at least one hardware form of a digital signal processor (DSP), a field programmable gate array (FPGA), a programmable logic array (PLA) and an ASIC (Application Specific Inte...
Embodiment 2
[0069] see figure 2 The shown method for segmenting fibular head and tibial head in DR knee joint anteroposterior film in quality control is applied to a mobile terminal, and the method can be executed by the processing device provided in the foregoing embodiment, and the method specifically includes the following steps:
[0070] S110. Acquire at least one DR knee joint image, and preprocess the DR knee joint image by thresholding;
[0071] Specifically, in order to be compatible with various shooting ranges and DR knee joint images of various manufacturers, preprocessing is performed here. If the range is large, the image including both legs is segmented to obtain a single knee joint image.
[0072] S120. Using the fuzzy C-means clustering method to segment the fibula and tibia in the preprocessed DR knee joint image;
[0073] It should be noted that the fibula and tibia were segmented using the fuzzy C-means clustering method (FCM). Because the fibula and tibia overlap at...
Embodiment 3
[0110] For the method for dividing the fibular head and tibial head in the DR knee joint anteroposterior film in quality control provided in Example 2, the embodiment of the present invention provides a device for dividing the fibula and tibial head in the DR knee joint anterior view film in quality control, Applied to mobile terminals, including:
[0111] A preprocessing module, which acquires at least one DR knee joint image, and preprocesses the DR knee joint image by thresholding;
[0112] Segmentation module, using the fuzzy C-means clustering method to segment fibula and tibia in the DR knee joint image after preprocessing;
[0113] The overlap acquisition module determines the edge of the overlapping part of the fibula and the tibia through edge detection;
[0114] a lateral edge acquiring module, configured to acquire the outer edge of the fibula;
[0115] The judging module judges whether the overlapping amount meets the standard according to the edges on both sides...
