Label:RETHINKDB is a Open-source distributed database built to store JSON and scale with very little effort. Self compared with MongoDB, RETHINKDB are aiming to being developer friendly all the while maintaining an operations oriented Approach of being highly available and high scale.Prior to version 1.16, original intentions from RETHINKDB is a system to push out changes from database level to Speciali Zed data stores like ElasticSearch or messaging

unfortunately hung and does not affect other systems.If the biz framework hangs up, can you quickly resume running?Of course, the Biz Framework saves the filename and position of the event after each event, so if the service hangs, you can set the filename and position to appear after the MySQL server is connected, such as: Binlog_ Set_position ($link, $filename, $position).Downstream (BS) if you hang up, can you recover quickly?This is a very critical issue, and if BS hangs it needs to rebuild

The "effect" of CG images is the most important. As for the technology used to achieve this effect, everything is transparent to the audience. Even Pixar thinks that only one bounce indirect illumination is sufficient for building a realistic and credible illumination effect. I think you will have a new understanding of realtime Gobal illumination. I have achieved a true and trusted indirect illumination effect. Compared with the Mental Ray attached t

to the x-y plane. Then we can obtain a hand mask (that is, remove redundant information from the depth graph through binarization. For example, we set the value of depth to 0 if it is less than M, 1. that is, the points out of this range are removed ). At this time, we Initialize an extreme point on this mask as the starting point, and then calculate the distance from the ground (I think it is the closest distance between the two points on the surface ). When the distance from the ground wire i

An Analysis of the meaning is about to give a string of cows, and then find a substring that spans the longest distance so that there are as many white cows as those in the range. White Cows can be painted as white cows. Since "White ox can be painted as a flower Ox", we need to find the longest substring so that the length is even and the number of white ox> = flower ox. Note that "maximum" does not mean the maximum number of elements. Sort the orders by the ox, then it will be online. Then

The output is a hand-fitting model (48 sphere model ). The 3D point cloud data here is represented by P, and each sphere is represented by SX. The center of the I-th sp

through finger detection. If we still find f finger, we can use PCA to analyze the finger's principal component, that is, the finger's direction. This is two constraints (it should be a vector) when you find a finger amount, the actual spatial position of the fingertip is fixed. Here there are three constraints (known ). When we remove the point clouds of our fingers, we have only the palm left. At this time, we can use PCA to analyze the direction of the palm. Here are three constraints (not

complicated gestures. But this is already the best method.Summary: This article uses Intel's gesture camera to obtain deep images and then convert them into 3D point cloud. Introduce the cost function. Then, the finger position is detected (the 2D + 1d representation is used), and the constraint is formed by the detected finger position for the initialization of the gesture, the optimal solution of cost function equation is optimized by the ICP-PSO algorithm, and the result of the gesture is ob
