  • QUANTIZATION METHOD, IMAGE PROCESSING APPARATUS, AND RECORDING MEDIUM
    Publication number: 20150049366
    Abstract: A quantization method according to an aspect of the present invention includes the steps of quantizing a first image data by the use of a basic pattern and converting the first image data into a second image data that represents a binary or multi-level quantized pattern having a gray level smaller than that of the first image data. The basic pattern according to this aspect of the present invention presents high frequent occurrence of the basic tone patterns and a mostly uniform-distributed pattern of the clusters of different kinds of the basic tone patterns in the image with the long-distance autocorrelation (periodicity) of the basic tone patterns suppressed. Quantization by the use of this basic pattern provides a quantized pattern that reflects pattern characteristics of the basic pattern.
