Eye image processing method and device

Abstract

Embodiments of the present invention provide an eye image processing method and apparatus. The method comprises: determining an orbit region of an image; obtaining a first mask image of the orbit region; determining at least one first abnormal region of the orbit region according to the first mask image; determining a first candidate abnormal eye region in the at least one first abnormal region according to abnormal eye region judgment conditions corresponding to the first mask image, the first candidate abnormal eye region meeting all judgment conditions among the abnormal eye region judgment conditions corresponding to the first mask image; and determining that the first candidate abnormal eye region is the abnormal eye region of the orbit region when the confidence of the first candidate abnormal eye region is greater than a seventh preset value. The method and the apparatus in the embodiments of the present invention can position an abnormal eye region of an eye image more accurately, thereby providing accurate position information for processing an abnormal eye.

Description

technical field [0001] Embodiments of the present invention relate to the field of image processing, and more specifically, to an eye image processing method and device. Background technique [0002] In low-light environments, the pupils of the human eye dilate to allow more light to pass through. If the flash is turned on when shooting, the capillaries on the retina of the fundus will be photographed. Depending on the lens and shooting scene, the photos taken will appear in different colors (commonly such as red, gold, white, etc.), called red eye / The golden eye phenomenon. [0003] For common mobile phones and digital cameras, because the "lens" and the "flash" are often very close, the "red-eye phenomenon" is more likely to occur. Generally, the pre-flash of the flash is used to suppress red-eye. The disadvantage is that it is not conducive to capture and the elimination effect is limited. [0004] Since red-eye / gold-eye are mostly shot in low-light scenes, the condit...

Problems solved by technology

Generally, the pre-flash of the flash is used to suppress red-eye. The disadvantage is that it is not conducive to capture and the elimination effect is limited.

[0004] Since red-eye / gold-eye are mostly shot in low-light scenes, the conditions of red-eye / gold-eye shooting vary greatly. For example, due to makeup and other reasons, the eyelids will appear red, and wearing glasses will cause the spectacle lens to have a golden reflection, and the white of the eye will appear golden-like. In other cases, the non-red-eye / gold-eye area cannot be completely excluded by using the simple threshold exclusion method, and it may cause false elimination
