摘要： An image is divided into subbands by wavelet transform using the Haar function as the base, and the lowest-frequency LL subband is entirely encoded. LH, HL, and HH subband coefficients which belong to the wavelet decomposition level of each hierarchy are then encoded such that coefficients at the same spatial position are encoded at once. The decoding side first decompresses the lowest-frequency LL subband, and then decodes sets of the LH, HL, and HH coefficients at the same spatial position in the subband of each wavelet decomposition level one by one. The decoding side immediately performs inverse wavelet transform by using the coefficient values, thereby obtaining the LL coefficient value of the next wavelet decomposition level. This makes it possible to sufficiently increase the processing speed even when the wavelet encoding/decoding is performed using a sequential CPU.
摘要翻译：图像通过使用Haar函数作为基底的小波变换被划分为子带，并且最低频率LL子带被完全编码。然后对属于各层次的小波分解级别的LH，HL和HH子带系数进行编码，使得在同一空间位置的系数一次被编码。解码侧首先对最低频率LL子带进行解压缩，然后逐个地对每个小波分解级别的子带中的相同空间位置处的LH，HL和HH系数的集合进行解码。解码侧通过使用系数值立即执行逆小波变换，从而获得下一个小波分解电平的LL系数值。这使得即使当使用顺序CPU执行小波编码/解码时，也可以充分提高处理速度。
