Embodiment Construction

[0031] The hardware part of the present invention is composed of a single video shooting device, an arithmetic processing device, and a display device. The core idea is to use the target recognition, target registration and target secondary projection in the video image to realize the video image displayed in the display device by the observer's eyes. .

[0032] Such as Figure 7 As shown, the present invention discloses a method for correcting eye images in a selfie video, comprising the following steps:

[0033] Step 1, target eye image detection and positioning: detect and locate the position of the eye from the video image;

[0034] The first step includes the following steps: step 11, preprocessing the image of the selfie video; step 12, identifying the face image from the image of the selfie video; step 13, identifying the left face image from the face image according to the grayscale method , the image of the right eye.

[0035] Step 11, preprocessing the image of th...

Abstract

The invention discloses a method for adjusting an eye image in a self-photographed video, which comprises the following steps of: 1, detection and positioning of a target eye image: detecting and positioning the position of an eye from a video image; 2, identification and positioning a sclera image, an iris image and a pupil image in the eye image: identifying the sclera image and the iris image according to the gray scale, identifying the iris image and the pupil image according to the texture, and positioning relative positions of the sclera image and the iris image, the iris image and the pupil image; and 3, secondary projection of the iris image and the pupil image: translating the iris image and the pupil image to the center of the sclera image so as to realize the adjustment of the eye image. The images are processed by a software method without increasing an additional device so that the active video image of the eye watching a display device can be acquired on the display device when the human face faces the display device and the eyes do not watch a pick-up lens, and the improvement cost of a hardware system is greatly reduced.

Description

technical field [0001] The invention relates to the field of video data processing and imaging, in particular to a method for adjusting eye images in selfie videos. Background technique [0002] In the application field of digital video processing, especially with the popularization of 3G communication network, the application of video Selfie and network video becomes more and more extensive. At present, there is a very disturbing status quo, that is, video capture devices are generally located near the outer edge of the display device, such as figure 2 shown. In this case, when the person being photographed looks at the screen of the display device, the imaging result on the display device is that the gaze point of the eyes deviates from the screen of the display device. In short, it is the face display image obtained by the screen observer The image of the middle eye is crooked, not facing up. The "face up" and "non-face up" of the eye image perceived by human vision are...
