Forensic science it the study of objects that relate to a crime. Forensic scientists study evidence so that it can be used in a court of law. Forensic scientists observe, classify, compare, use numbers, measure, predict, interpret data, and draw inferences based on evidence. In this lesson, students will use these science inquiry skills.In this dental image was classify by sift algorithm

该压缩包实现二维的DCT变换和逆DCT变换，可以对图像做DCT变换和逆DCT变换，实现非常简洁，速度很快。(the compressed 2D DCT and the inverse DCT. Images can be done DCT and inverse DCT achieve a very simple, very fast.)

该算法把计算出的图像不变质心作为对其进行对数极坐标变换的原 点, 再作傅立叶变换, 取出中频段幅值作为水印嵌入域。该算法具有较好的鲁棒性、可检测性, 能同时抵抗几何攻击和信号 处理攻击, 它在数字图像的版权保护等领域有广泛的应用前景。(The algorithm to calculate the heart of the image does not degenerate as the number of its polar transformation of the origin, further Fourier transform, remove the watermark embedding in the frequency domain as amplitude. The algorithm has better robustness, detectability, can also resist geometric attacks and signal processing attacks, which in the digital image copyright protection and other fields have a wide range of applications.)

到达时间差（TDOA）源位置估计 -------------------------------------------------- ---------- 使用麦克风信号和自由场模型之间的延迟源位置估计。 TDOA_pairs.m 估计延迟（相对于通道1）通过互相关在时域中。 TDOA_pairs_GCC.m 估计在频域中的延迟（相对于信道1）。采用广义互相关 和SCOT或PHAT（或没有）的均衡。 PHAT的建议，以避免因周期分量的含糊之处。 TDOA_to_sourcepos.m 估计源位置（距离和垂直RESP。水平偏移量）从之间的延迟 阵列麦克风信号。假设一个自由场。(Direction of arrival (DOA) estimation ------------------------------------- Direction-of-arrival estimation with a free field, far field model. Narrowband or broadband (non-coherent) processing. DOA_Bartlett.m Bartlett (delay-and-sum) steered response power. DOA_Bartlett_Octave.m Bartlett (delay-and-sum) steered response power within nth octave frequency bins. DOA_MUSIC.m MUSIC based pseudo beamform power. DOA_MUSIC_Octave MUSIC based pseudo beamform power. nth octave filtering.)
