* Zooming and Shrinking Images -(a) Write a computer program capable of zooming and shrinking an image by nearest neighbour and bilinear interpolation. The input to your program is the desired size of the resulting image in the horizontal a

* Frequency domain filtering -1. Discrete Fourier Transform Write a C++ function for each of following: (a) Multiply the input image by (-1)x+y to center the transform for filtering. (b) Compute the two-dimensional discrete F

：MPEG-4是当前最具影响的多媒体数据压缩编码国际标准。针对视频编码过程中计算复杂度高，系统运算量大等 特点，本文提出了在TMS320C6416T上实现MPEG-4编码的优化方法。为使MPEG-4编码器达到实时应用的要求，结 合C64x DSP的特点，采取了一系列软件优化方法，包括合理分配存储器，在内存开辟双缓冲区结构，用汇编程序实现 MPEG-4的核心算法以及对整个程序流程进行C语言级优化等。实验结果表明，该编码器可以对768 pixel×576 pixel， 25 fram
