Quantization is a compression technique used in image processing that reduces a range of values to a single quantum value. It is the process of converting a sampled image with real values to one with ...

Colour quantization, the process of reducing the number of distinct colours in an image while maintaining visual fidelity, is a cornerstone of digital image processing and computer graphics. Rooted in ...

The Color Quantization App is a Python-based application that reduces the number of distinct colors in an image while preserving its visual appearance. This technique is useful for image compression, ...

Abstract: Color quantization is an important operation with many applications in image compression and image analysis. Through color quantization, millions of colors in original images are compressed ...

We study the perceptual problem related to image quantization from an optimization point of view, using different metrics on the color space. A consequence of the results presented is that ...

ABSTRACT: A face-mask object detection model incorporating hybrid dilation convolutional network termed ResNet Hybrid-dilation-convolution Face-mask-detector (RHF) is proposed in this paper.
