Tobacco leaf image quality evaluation method and system, storage, and electronic device

The present invention provides a tobacco leaf image quality evaluation method and system, a storage, and an electronic device. The method comprises the steps of: extracting the component value of eachpixel of a tobacco leaf image to be evaluated in a color space, wherein the color space is formed by yellow color gamut components, bright color gamut components and a black color gamut components; calculating the color gamut indexes of the pixels according to the component values of pixels; determining the quality evaluation indexes of the pixel according to the color gamut indexes of the pixels; and calculating an average value of the quality evaluation indexes, comparing the average value with a preset quality evaluation index, and determining the quality condition of the tobacco leaf image to be evaluated. The tobacco leaf image quality evaluation method and system, the storage, and the electronic device employ the color gamut indexes to perform tobacco leaf image quality evaluation,and are lower in complexit
