[Industry research] Image-Hashing-based-on-Human-Visual-System DL : 0: 提出一种基于视觉特性的图像摘要算法，增大人眼敏感的频域系数在计算图像Hash时的权重，使得图像Hash更好地体现视觉特征，并提高鲁棒性。将原始图像的分块DCT系数乘以若干由密钥控制生成的伪随机矩阵，再对计算的结果进行基于分块的Watson人眼视觉特性处理，最后进行量化判决产生固定长度的图像Hash序列。本算法比未采用视觉特性的算法相比，提高了对JPEG压缩和高斯滤波的鲁棒性。图像摘要序列由密钥控制生成，具有安全性。-Based on the visual characteristics of the image digest algorithm, increasing the human eye-sensitive frequency-domain coefficients in the calculation of the image when the weight of Hash, Hash makes images better reflect the visual characteristics, and improve robustness. Will block the original image multiplied by the number of DCT coefficients generated by the key control of pseudo-random matrix, then the results of calculation based on the sub-block of Watson HVS treatment, and finally quantify the judgments arising from fixed-length sequence of images Hash . Than the algorithm did not use the visual characteristics of the algorithm, improve the JPEG compression and Gaussian filtering robustness. Abstract image sequence generated by the key control, with security.

[Industry research] Redis-deployment-on-windows DL : 0: redis是一个key-value存储系统。和Memcached类似，它支持存储的value类型相对更多，包括string(字符串)、 list(链表)、set(集合)、zset(sorted set –有序集合)和hash（哈希类型）。这些数据类型都支持push/pop、add/remove及取交集并集和差集及更丰富的操作，而且这些操作都是原子性的。在此基础上，redis支持各种不同方式的排序。与memcached一样，为了保证效率，数据都是缓存在内存中。区别的是redis会周期性的把更新的数据写入磁盘或者把修改操作写入追加的记录文件，并且在此基础上实现了master-slave(主从)同步。Redis一般部署在linux服务器上，但是我们也可以在windows上学习他的安装和配置。-redis is a key-value storage system. And Memcached Similarly, it supports value type of storage is relatively more, including string (string), list (list), set (set), zset (sorted set- ordered sets) and hash (hash type). These data types are supported push/pop, add/remove and take the intersection of union and difference operations and richer, and these operations are atomic. On this basis, redis support a variety of different ways of sorting. Like with memcached, in order to ensure efficiency, data is cached in memory. Redis difference is periodically updated data written to disk or to write the modified operating additional log files, and on this basis to achieve a master-slave (master-slave) synchronization. Redis ships deployed on the linux server, but we can also learn his installation and configuration on the windows.
