Problems solved by technology

However, there is no relevant literature on the index evaluation of fundus image registration.
[0003] In view of the problem that the existing technology only registers the fundus image when realizing the registration of the fundus image, and does not involve the evaluation and analysis of the matching index after the registration of the fundus image, no effective solution has been proposed yet

Embodiment 1

[0023] According to an embodiment of the present invention, a method embodiment of an image processing method is provided. It should be noted that the steps shown in the flowcharts of the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, and, Although a logical order is shown in the flowcharts, in some cases the steps shown or described may be performed in an order different from that shown or described herein.

[0024] figure 1 is an image processing method according to an embodiment of the present invention, such as figure 1 As shown, the method includes the following steps:

[0025] Step S102, acquiring a first fundus image and a second fundus image obtained by photographing the same fundus at different periods.

[0026] Specifically, the first fundus image may be a fundus image base map, which may be a fundus image taken by a person many years ago, and the second fundus image may be a fundus image to be register...

Embodiment 2

[0057] According to an embodiment of the present invention, a product embodiment of an image processing device is provided, Figure 7 is an image processing device according to an embodiment of the present invention, such as Figure 7 As shown, the device includes an acquisition module 101 , a conversion module 103 , a comparison module 105 and a determination module 107 .

[0058] Among them, the acquisition module 101 is used to acquire the first fundus image and the second fundus image obtained by photographing the same fundus in different periods; the conversion module 103 is used to convert the first fundus image and the second fundus image into binarization It is the first black-and-white image and the second black-and-white image; the comparison module 105 is used to compare the similarities and differences between the first black-and-white image and the second black-and-white image; the determination module 107 is used to determine that the fundus has changed when the ...

Abstract

The invention discloses an image processing method and apparatus. The method comprises the steps of obtaining a first eye fundus image and a second eye fundus image obtained by shooting a same eye fundus in different periods; performing binarization processing on the first eye fundus image and the second eye fundus image, and converting the first eye fundus image and the second eye fundus image into a first black-white image and a second black-white image; comparing similarities and differences of the first black-white image and the second black-white image; and when the similarities and differences meet a predetermined condition, determining that the eye fundus is changed. According to the method and the apparatus, the technical problems that only the eye fundus images are registered and matching index evaluation and analysis after eye fundus image registration are not involved during eye fundus image registration in the prior art are solved.

Description

technical field [0001] The present invention relates to the field of computer internet, in particular, to an image processing method and device. Background technique [0002] With the development of computer technology, advanced computer image processing technology has been used in the processing and analysis of fundus images, providing a modern scientific means for rapid, accurate and objective analysis of fundus images. Fundus image registration technology has been widely used in assisting ophthalmology diagnosis and treatment. By registering fundus images, doctors can better diagnose and detect various diseases related to the fundus, such as the diagnosis of diabetes, glaucoma, macular deformation, etc., and the detection of myopia. For example: for the detection of myopia, the direct method is that the doctor observes and compares the optic disc of the fundus image in different periods, and judges myopia according to the bump of the optic disc and the change of the bloo...
