I've found a selution when working with cannon.js. cannon.js has a kind of update function so you can use .pinLastValue() because it does this every frame in order to update the physics.

Can't get FaceTracker class to work on HoloLens 2

Asked 2020-Jul-14 at 11:23

I'm having trouble getting the FaceTracker Class to work on HoloLens 2. As soon as I try to detect the faces with ProcessNextFrameAsync Method I get an exception of the following kind:

System.Runtime.InteropServices.COMException (0x80004005): Unspecified error

This is only the first part of the error message, if more information is needed, I can add that.

See this for a minimal example.

This is an official sample show how to use the FaceTracker class to find human faces within a video stream: Basic face tracking sample. And in line 256, that is the main point to get a preview frame from the capture device.

However, base on your code, you have created a VideoFrame object and specified the properties and format to it, but you are missing invoke GetPreviewFrameAsync to convert the native webcam frame into the VideoFrame object.

You can try the following code to fix it:

frame.getBitmap() will only return a value if the frame was originally created from a bitmap. CameraSource supplies image information as ByteBuffers rather than bitmaps, so that is the image information that is available.

frame.getGrayscaleImageData() will return the image data.

frame.getMetadata() will return metadata such as the image dimensions and the image format.

I am new to ios. Currently I am working on an app that uses opencv facetracker. Therefore I use C++ within Objective-C. My problem is, that the contructor of the C++ class, which handles the facetracking part, needs the file location of the cascade file. The Constructor looks like this:

I have found the solution. User r4ghu was right. But it was not clear for me, where to put that lines of code. If you want to load your cascade file correctly you would have to do that before you initialize your camera. For example:

UWP use face tracking on video playback

Asked 2017-May-20 at 02:03

In UWP it seems very easy to use FaceTracker on video capture from say the device camera. But I need to use it on video playback. Anyone has any suggestions how it can be done or any alternative paths to achieve similar result?

I would like however to have the code running locally (on the same machine or on the local network server) as opposed to calling Web services and sending them thousands of frames non stop.

*the easiest would be to: 1. convert video playback to a capture stream 2. use tracker to detect faces and also draw rectangles 3. display result as a video

I understand step 2 is all taken care of by Microsoft. I think 3 is easy. So anyone knows how to achieve step 1?*

...

ANSWER

Answered 2017-May-20 at 02:03

You can't convert the video playback to a capture stream, but you can get the VideoFrames from the MediaPlayer by registering a custom video effect with the MediaPlayer's AddVideoEffect method.

The custom video effect is a class which implements IBasicVideoEffect. Its ProcessFrame method will be passed a ProcessVideoFrameContext object which contains a InputFrame you can pass to the FaceTracker and an OutputFrame which you can modify with the rectangles from the FaceTracker.

See the custom video effects documentation for a walkthrough on creating and registering an effect in your app. For example purposes, it demonstrates applying the effect to a MediaComposition clip rather than to a running MediaPlayer, but the same effect class can be used in both places.

QUESTION

Using Python to rearrange .txt rows and columns

Asked 2017-May-07 at 22:33

I am a very novice coder who needs help combining and rearranging a lot of .txt data. I have 500 text files (actually there are .pts files, but that seems to be the same thing as .txt) with facial landmark coordinates extracted from photographs of people using CLM Facetracker. The output for each photo is like this (68 rows down):

version: 1

npoints: 68 {

216.512 146.425

217.526 166.783

219.63 187.059

(....)

}

which is equivalent to:

x1,y1

x2,y2

I wish to rearrange it so instead all the 68 landmark coordinates are in a single row with a comma in between each:

216.512, 146.425, 217.526, 166.783, 219.63, 187.059

x1, y1, x2, y2

Is there a simple way to do this? Ideally I would also like to add zeros so all landmark coordinates have the same amount of decimal places. Thanks in advance, and apologies if I am missing something super obvious :)
