N=11，41，81，121时，用矩形窗设计一个低通FIR滤波器，其剪切频率wc＝0.3л(N = 11,41,81,121, the rectangular window design with a low-pass FIR filter, its cut frequencies wc = 0.3л)

In image processing, a Gabor filter, named after Dennis Gabor, is a linear filter used for edge detection. Frequency and orientation representations of Gabor filters are similar to those of the human visual system, and they have been found to be particularly appropriate for texture representation and discrimination. In the spatial domain, a 2D Gabor filter is a Gaussian kernel function modulated by a sinusoidal plane wave. The Gabor filters are self-similar: all filters can be generated from one

用互相关法实现时延差估计，时延差是使用TDOA算法实现定位的关键步骤！！！(use cross correlation function to estimate the time delay，time difference is a very important parameter when using the TDOA algorithm to positioning！)

Multiple kernel learning is a model to merge multiple kernels by linear combination. Mostly solving the models are slow due to explicit computation of kernels. Here, we propose to approximate kernel map function explicitly in finite dimensional space. Then, we use dual coordinate descent to solve the SVM. By storing the solutions in primal, we do not have to compute the kernel explicitly. A group lasso regularization on kernel weights is solved with SVM alternatingly. This is a side-project in my research projects with Dr. Yi-Ren Yeh and Dr. Frank Wang in Academia Sinica.
