1. 编程实现图像DFT和DCT高通、低通滤波。并进行比较 2. 找一幅曝光不足的灰度（或彩色）图像，按照直方图均衡化方法进行处理 3. 打开一幅图像，利用Roberts梯度法、Sobel算子和拉普拉斯算子进行锐化，并比较结果 4. 对清晰图像进行模糊化，并实现迭代盲目反卷积（IBD）图像恢复算法 5. 编写一个程序，对输入的图像进行哈夫曼编码，显示原图像的熵、编码后的平均码字长度、并能够根据编码重建出图像。

This package works on Ubuntu 12.04 and 14.04. ## Version History * **0.0.4**: - Fixed issue where packets would be dropped if the header checksum was broken up into multiple packets. - Added `verbose` option. * **0.0.3**: - Replaced `decimation` options with `rate` options. Decimation is automatically calculated. - Added a file for use with Kalibr. - Added a udev rule to configure permissions. * **0.0.2**: - Units of acceleration are now m/s^2, in agreement with ROS convention. - Cleaned up code base, replaced error codes with exceptions. - Status can now be viewed from `rqt_runtime_monitor`. - Filter output is now in a single, custom message with covariances and important status flags. - Added option to enable/disable accelerometer update in the estimator. - Removed TF broadcast option. - Reformatted code base to clang-llvm convention. * **0.0.1**: - First release.
