Embodiment Construction
[0018] The specific implementation of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0019] figure 1 It is a flowchart of a method for preprocessing medical image pictures according to an embodiment of the present invention. Such as figure 1 As shown, the preprocessing method of the medical image picture includes:
[0020] Step S101: using an edge detection algorithm on the medical image to detect the concentrated text area of the above medical image;
[0021] Step S103: Based on the upper left corner of the above-mentioned medical image picture, establish the pixel distribution statistics F(x, y) on the y-axis based on the x-axis and the pixel distribution G(y, x) on the x-axis based on the y-axis;
[0022] Step S105: Regarding the pixel distribution information of the above-mentioned F(x, y) and the above-mentioned G(y, x), when the edge of the above-mentioned character-concentrated area is a character and a blan...

The invention discloses a method and device for preprocessing medical image pictures. The method comprises: adopting an edge detection algorithm to the medical image pictures to detect the concentrated text area of the medical image pictures; Pixel distribution statistics F(x, y) on the y-axis based on the x-axis and pixel distribution G(y, x) on the x-axis based on the y-axis; pixel distribution for F(x, y) and G(y, x) Information, when the edge of the text concentration area is text and blank, use the gradient method of setting step size n to judge whether the edge of the text concentration area is the junction point between the blank area and the text area, and the edge of the text concentration area is the table line and When it is blank, judge whether the edge of the text concentration area is the junction point between the region of interest and the blank region according to the distribution stability of adjacent pixels; use the obtained junction points to construct the circumscribed matrix of the region of interest and cut it out.
Description
technical field [0001] The present invention relates to the communication field, in particular to a method and device for preprocessing medical image pictures. Background technique [0002] With the rapid development of science and technology, the high popularity of the Internet has greatly shortened the distance and time of interaction between people, thus driving the rise of Internet hospitals. Internet hospitals have brought us a lot of convenience, benefiting the public, especially in the relatively remote and backward areas, allowing the public to consult famous experts and professors in Beijing, Shanghai, Guangzhou and other regions without leaving home; not only save the public travel expenses, but also The most important thing is to shorten the patient's consultation and medical treatment speed, and bring convenience for many patients to seek medical treatment in time. [0003] Internet hospitals mean the networking of consultations, including the digitization of ex...
