It considered the spatial information of images (which was often neglected), and segmented an image following two steps: color quantization and spatial segmentation.
该方法充分考虑到图像的空间信息，对图像的分割采用两个步骤：颜色量化和图像空间分割。
The watermark was embedded in the wavelet domain using the mean quantization method. This method can be used to detect the distortion both in spatial and frequency domain.
这种算法是采用了均值量化的方法，把数字水印嵌入图像的离散小波域，可以检测在空间域和频率域的图像失真。
The methods for both color quantization and color spatial vector quantization using palette are studied in this paper.
本文研究了用调色板技术进行色彩量化和彩色空间量化的方法。
