Embodiment Construction

[0054] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0055] refer to figure 1 , the first embodiment of the color consistency method of the present invention provides a color consistency method, the color consistency method includes:

[0056] Step S10 acquires each image sample collected by the first image acquisition device, and extracts pixel points of each image sample respectively.

[0057]In the present invention, the images collected by the image collection devices are color-corrected, so that the images collected by different image collection devices are consistent in color. The present invention can be applied to the color correction of tongue images, and can also be used for other types of images, so as to realize the color consistency of images collected by different image collection devices.

[0058] In this embodiment, the color of the tongue image is cons...

Abstract

The invention discloses a color consistency method. The method comprises the steps of obtaining image samples collected by a first image collection device, and extracting pixels of the image samples; clustering the pixels according to preset cluster quantity, thereby obtaining color cards corresponding to the cluster quantity; calculating the color correction errors of the color cards based on the images of the color cards collected by a second image collection device; selecting the color card with the lowest color correction error in the color cards as a correction color card, and correcting the images collected by the second image collection device based on the correction color card. The invention also discloses a color consistency device. According to the method and the device, after the images collected by the second image collection device are corrected through the correction color card, the colors of the corrected images are keep consistent with the colors of the images collected by the first image collection device, and the color consistency of the images collected by different image collection devices is realized.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a color consistency method and device. Background technique [0002] Traditional Chinese medicine pays attention to observation, hearing, and inquiring. In inspection, the diagnosis of diseases is mainly based on the color of the patient's tongue. With the development of modern medical technology, the patient's tongue image can be collected by image acquisition equipment, which can be used for disease diagnosis and record storage of diagnosis and treatment records. Therefore, the color of the tongue image collected by the image collection device plays a key role in tongue diagnosis. [0003] At present, different hospitals or medical institutions use different tongue diagnosis image acquisition equipment, and different image acquisition equipment may have different colors of the tongue images collected from the same patient due to factors such as camera quality and ligh...
