傅里叶谱与频域低通滤波
说明: 傅里叶谱与频域低通滤波 (a)从图书网站下载图4.41(a)并计算其(居中)傅里叶谱。(b)显示频谱。(c)在等式(4.8-7)中实现高斯低通滤波器。您必须能够指定结果2D函数的大小,M x N。此外,您必须能够指定高斯函数的中心位置。(d)从图书网站下载图4.41(a),并对其进行低通滤波,以复制图4.48中的结果。(Fourier Spectrum and Lowpass Filtering in Frequency Domain
(a) Download Fig. 4.41(a) from the book web site and compute its (centered) Fourier spectrum.
(b) Display the spectrum.
(c) Implement the Gaussian lowpass filter in Eq. (4.8-7). You must be able to specify the size, M x N, of the resulting 2D function. In addition, you must be able to specify the location of the center of the Gaussian function.
(d) Download Fig. 4.41(a) from the book web site and lowpass filter it to duplicate the results in Fig. 4.48.)

some fast feature extraction algorithms are addressed for joint retrieval of images
compressed in JPEG and JPEG2000 formats. In order to avoid full decoding, three fast algorithms that
convert block-based discrete cosine transform (BDCT) into wavelet transform are developed, so that
wavelet-based features can be extracted from JPEG images as in JPEG2000 images.
