The invention discloses a color
high contrast processing algorithm for four-color
electronic paper, and relates to the technical field of
electronic paper display technology and
image processing, and the method comprises the specific steps: firstly, carrying out
feature extraction, converting an original
RGB image to an HSV space, carrying out the statistics of the pixel proportion of a brightness interval, screening red and yellow pixels, and calculating the feature and the proportion of four colors; a
dynamic clustering center is generated; performing weighted clustering mapping to generate an
intermediate image; enhancing the saturation and boundary contrast of the adaptive image in a linkage manner; and finally, modular adaptive output: selecting scheme optimization data, converting the scheme optimization data into a 2-bit format, and outputting the two-bit format after
verification. According to the method, through multi-dimensional
feature extraction and
dynamic clustering center generation, accurate
color mapping is realized, and the color rendition degree and comfort degree are improved; and through multi-factor linkage enhancement and modular adaptive output design, the display effect and hardware adaptability are considered, the detail expressive force is enhanced, the integration process is simplified, reliable
data transmission is guaranteed, and the application
adaptation and display quality is improved.
