问题 I'm just trying to save same frames on video from a buffer, where I properly saved the Bitmap Frame, and the Time Stamp, of the frame. writer1 = new VideoFileWriter(); this.writer1.Width = this.videoSourceEndo.VideoResolution.FrameSize.Width; this.writer1.Height = this.videoSourceEndo.VideoResolution.FrameSize.Height; this.writer1.VideoCodec = VideoCodec.H264; this.writer1.BitRate = (this.videoSourceEndo.VideoResolution.FrameSize.Height * this.videoSourceEndo.VideoResolution.FrameSize.Width *

问题 I am using OpenFace Windows binaries and Accord .NET to create a C# version of this Python-based face recognition system. OpenFace does most of the work, I just need to train an SVM to classify an unknown face (with probability), using known faces as the output classes. A "face" in this context is a CSV file full of face measurements. Simple enough in theory. As this seems best done with one-vs-rest methods, I am trying to work from the MulticlassSupportVectorMachine example in the API.

问题 I am using accord.net. I have successfully implemented the two Decision tree algorithms ID3 and C4.5, now I am trying to implement the Naive Bays algorithm. While there is a lot of sample code on the site, most of it seems to be out of date, or have various issues. The best sample code I have found on the site so far has been here: http://accord-framework.net/docs/html/T_Accord_MachineLearning_Bayes_NaiveBayes_1.htm However, when I try and run that code against my data I get: There are no

问题 I wanted to use something from Accord library as well as the AForge library. But when I installed it, I started getting the following error: Error CS0433 The type 'IntPoint' exists in both 'AForge, Version=2.2.5.0, Culture=neutral, PublicKeyToken=c1db6ff4eaa06aeb' and 'Accord, Version=3.0.2.0, Culture=neutral, PublicKeyToken=fa1a88e29555ccf7' On this line of code: startingPoint = new IntPoint(point.X, point.Y); How can I ensure that I only use the original AForge DLL for this? Is there

问题 I am working on an Augmented Reality project using ARCore. Coordinate system of ARCore changes every time you launch the application making the initial position as origin. I have 5 points in another coordinate system and i can find 4 of these positions in Unity world space using ARCore Augmented Image. These points have different values in my other coordinate system of course. I have to find position of a 5th point in Unity world space using its position in other coordinate system. I have

问题 I have a system of linear equations with dimensions 3xN that I am currently solving using the Accord.NET method: double[,] A = ... // matrix A double[] b = ... // vector b // Then all that is necessary is to call: double[] x = A.Solve(b, leastSquares: true); This works fine but I need to also impose constraints (primarily, x > 0). Is there a way to implement this (ideally within Accord or some other simple library)? The elements of both A and B can have positive, negative and zero values and
