The ability to create great applications does not necessarily mean success in business, and there is still much work to be done, and it is no longer possible to announce a "knock-out" after simply releasing the application. You need to be able to quickly make adjustments based on user feedback, test new features, and provide users with the content they care about most.Firebase remote configuration is the result of this. With Firebase remote configurat

In the early stages of development, many companies benefited from its ease-of-use and economy. With the growth of these companies, more and more companies into the development of MySQL, so the characteristics of MySQL more and more rich, such as: different characteristics of the stor

The upload class is used in the service layer. Notice it has a constructorfilefor attribute, and which has a type ofFile. This would allows us to initialize new uploads with a JavaScript File object. You'll see what's important in the next step.

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.

Realtime and robust hand tracking from cost function learning in Depth
First, we should know what the input data is: 3D point cloud data.
3D point clouds give me this feeling.
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
