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

I wanted to read the code and then write it in detail. But if someone asks, post it first! Some problems encountered during code debugging. First, you can download: http://download.csdn.net/detail/u012192662/8042147 here if you don't have code Then you need to install opencv (I think if you're doing this you should have); eigen; http://download.csdn.net/detail/u012192662/8042155 The author's Code uses opencv V2.1 and eigen v2.0.15. There is no problem with opencv. It is okay for later versions

AbstractWhy is ThinkPad so loyal to ThinkPad? Trackpoint allocation is one of the most important factors, which is also the biggest feature of ThinkPad. This article is the first release of the tracking trackpoint, hoping to help them quickly get started and develop the power of small checkpoints. IntroductionThe following table lists the locations of small metric points:1. Increase Work EfficiencySo that your hands do not need to open your mouse to

In the past few days, the weather on the island has suddenly changed. After all, my unlucky child has escaped from the cold and shot birds ~~~ In the past few days, I only wrote a simple code for gesture tracking. Principle: background difference + skin color detection. Background difference: Take the average value of the first 30 frames, calculate the sum of the difference between the first 30 frames, and then calculate the mean value. It is detected

Tags: blog http OS ar strong SP on log html Preface Template Matching and correlation coefficient method are typical methods of target tracking. They have many advantages: simplicity and accuracy, wide applicability, good noise resistance, and fast computing speed. The disadvantage is that it cannot adapt to drastic changes in light and severe deformation of the target. The template matching method is to find the target template location in a fra

(render).Using Peek to control dependencies (controlling dependencies using Peek)(Note: The specific role of peek is still useless, but also do some targeted scenes to do the verification, the current document-based understanding, may be to prevent circular reference when the role of relatively large)Knockout will automatically track dependencies, but sometimes it may not work for us, we may need to manually control which dependencies need to be updated (I have not yet encountered this scenario

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

Worth looking at the ICCV 2017 target tracking papers are as follows: 1) crest:convolutional residual Learning for Visual tracking. 2) Learning background-aware correlation Filters for Visual tracking. 3) Need for speed:a Benchmark for higher Frame Rate Object tracking. 4) Parallel

distributed network. When application A sends A request, dozens or more services may be called ". If we compare a distributed system to a highway network, each front-end request is equivalent to a high-speed vehicle, and the request processing application is a high-speed toll station, the vehicle traffic information is recorded as a log on the toll station, including the time, license plate, site, road, price, etc. If all the logs on the toll station are integrated, the complete traffic record

Block changetracking is a feature launched in Oracle 10 Gb. The official website defines block change tracking as follows: Adatabase option that causes Oracle to track data file Blocks Affected by eachdatabase update. the tracking information is stored in a block change trackingfile. when block change tracking is enabled, RMAN uses the record of changedblocks fro

Computer encryption anti-tracking technology ciphertext Technology 1) Tracking TechnologyWe all know that DOS has a powerful dynamic tracing debugging software debug, which can implementProgramIn fact, this is because of the single-step interruption and breakpoint interruption, and most of the current tracing debugging software uses these two interruptions. One-step interruption (int1) is an interruptio

Failure request tracking can be configured at two levels: -At the site level, you can enable or disable tracing and configure log file settings. -At the application level, you can specify failure conditions when capturing trace events, and you can also configure trace events that should be captured in log file entries. 　　(i) View a list of failed request tracking rules To manage the
