Embodiment Construction

[0026] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0027] Embodiments of the present invention propose a method for evaluating image quality based on EEG signals, the process of which is as follows figure 1 shown, including:

[0028] Such as figure 1 As shown, the image quality evaluation method based on EEG signal includes the following steps:

[0029] Step 1. Place electroencephalograph electrodes (ie, EEG electrodes) at the OZ position of the occipital lobe of the subject's head, place a reference electrode at the position of the auricle on one side, and place a grounding electrode at the position of the auricle on the other side; the signals collected through the three electrodes pass through After the differential amplifier and the analog-to-digital converter, the EEG signal of the subject is obta...

Abstract

The invention provides an image quality evaluation method based on an EEG signal. The method comprises steps that a stimulus graph is respectively generated according change of color saturation, white brightness and sharpness of a reference graph; the reference graph and the stimulus graph are sequentially and continuously displayed to a testee, and an EEG signal of the testee is simultaneously acquired according to whether the testee can distinguish the reference graph from the stimulus graph; a P300 wave peak value and incubation period data are acquired according to the acquired EEG signal of the testee, an incubation period is defined to be time duration from occurrence of stimulus to occurrence of a peak value, and the unit of the incubation period is commonly ms; an incubation period and peak value prediction model of each stimulus graph is acquired according to the color saturation, white brightness and sharpness stimulus graphs of the reference graph.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to an image quality evaluation method based on EEG signals. Background technique [0002] With the continuous development of display technology, consumers in modern society have higher and higher requirements for display technology. In the past, even a small blurry CRT screen would be enjoyable to watch as long as the image could move and have the right color. But now not only require the basic things such as large screen, clear image and rich colors, but more consumers start to care about deeper things. Especially as the concept of a healthy and comfortable life becomes more and more popular, people begin to pay attention to whether they are comfortable when viewing images and whether they are the image quality they most hope to achieve. Therefore, the research on image quality evaluation has become a hotspot in display technology research. [0003] The earliest researc...
