Face detection using matlab

In a multiple transmit antenna, single antenna per receiver downlink channel with limited channel state feedback, we consider the following question: given a constraint on the total system-wide feedback load, is it referable to get low-rate/coarse channel feedback from a large number of receivers or high-rate/high-quality feedback from a smaller number of receivers? Acquiring feedback from many receivers allows multi-user diversity to be exploited, while high-rate feedback allows for very precise selection of beamforming directions. We show that there is a strong preference for obtaining high-quality feedback, and that obtaining near-perfect channel information from as many receivers as possible provides a significantly larger sum rate than collecting a few feedback bits from a large number of users.

这是一个由我本人亲自编写的提取图像特定部分的MATLAB程序。通过使用这个函数，你可以轻而易举地将图像的特定位置用白色矩形线框加以圈定、显示。(If you want to circle the specific area of an image, this little program is much more practical and convenient, thus will help you to mark any area of the image with with rectangle.)
