Abstract: PURPOSE: A wavelet image coding method is provided to code a wavelet sequence in a fixed order for increasing memory capacity, thereby effectively removing motion blurs. CONSTITUTION: A wavelet image coding method comprises the steps of: receiving inputs about the previous frame data in RGB signals; transforming the RGB signals to YCbCr signals; segmenting the YCbCr signals into multiple one-dimensional blocks; transforming the multiple one-dimensional blocks to wavelet coefficients through discrete wavelet transform; storing the wavelet coefficients in a buffer after merging the wavelet coefficients into one sequence; and coding the sequence into a bit stream by n-pixel.

Abstract translation: 目的：提供一种小波图像编码方法，以固定的顺序对小波序列进行编码，以提高存储容量，从而有效消除运动模糊。 构成：小波图像编码方法包括以下步骤：接收关于RGB信号中的先前帧数据的输入; 将RGB信号转换为YCbCr信号; 将YCbCr信号分割成多个一维块; 通过离散小波变换将多个一维块转换为小波系数; 将小波系数合并为一个序列后，将小波系数存储在缓冲器中; 并通过n像素将序列编码成比特流。
