Abstract
(EN)
The present invention provides a method for recognizing a single-tone image. The method for recognizing a single-tone image comprises: converting a plurality of rgb optical values corresponding to a plurality of pixels into an HSV color model; forming a statistical histogram according to a plurality of tone values in the HSV color model respectively corresponding to the plurality of pixels, the statistical histogram comprising a plurality of bars, and the plurality of bars respectively corresponding to the quantities of pixels located in different tone value intervals; and determining, according to the quantity of bars, in the statistical histogram, having the quantities of pixels greater than a preset quantity threshold, whether an image is a single-tone image. The method can effectively recognize a single-tone image.

Cette invention concerne un procédé de reconnaissance qu'une image est monochrome. Le procédé de reconnaissance d'une image monochrome comprend : la conversion d'une pluralité de valeurs optiques rgb correspondant à une pluralité de pixels en un modèle de couleurs HSV; la formation d'un histogramme statistique selon une pluralité de valeurs de teintes dans le modèle de couleurs HSV correspondant respectivement à la pluralité de pixels, l'histogramme statistique comprenant une pluralité de barres, et la pluralité de barres correspondant respectivement aux quantités de pixels situés dans différents intervalles de valeurs de teintes; et la détermination, selon la quantité de barres, dans l'histogramme statistique, ayant les quantités de pixels supérieures à un seuil de quantité prédéfini, si une image est une image monochrome. Le procédé peut reconnaître efficacement une image à une seule teinte.

本发明提供一种识别单一色调影像的方法。该识别单一色调影像的方法通过将与多个像素对应的多个rgb光学值转换为HSV颜色模型,根据HSV颜色模型中分别与多个像素对应的多个色调值形成统计直方图,该统计直方图中具有多个直方条,所述多个直方条分别对应位于不同的色调值区间的像素个数,根据统计直方图中像素个数大于一预设的数量阈值的直方条的数量来判断影像是否为单一色调影像,可以有效识别单一色调影像。
