kandi X-RAY | FaceRecognition Summary
In this project, PCA, LDA and LPP are successfully implemented in Java for face recognition. After the system is trained by the training data, the feature space “eigenfaces” through PCA, the feature space “fisherfaces” through LDA and the feature space “laplacianfaces” through LPP are found using respective methods. Later in this report, W is used to represent the obtained feature space. Once W is obtained, training faces are projected to subspace defined by W to construct FaceDB. When an unknown face is needed to recognize, this test face is firstly projected onto subspace W. Afterward, the program finds the K nearest neighbors of the projected data in FaceDB. Finally, the class label is assigned to the test face according to the majority vote among the neighbors. This classification algorithm is known as K-nearest neighbor.

QUESTION
Is it a way of using a dependency from a project to another while they are in the same solution? For example:
...ANSWER
Answered 2021-Jan-24 at 20:04Use a project reference.
https://docs.microsoft.com/en-us/visualstudio/ide/managing-references-in-a-project?view=vs-2019
To test; create a new solution with two projects within it. Within one project, add a nuget package. Say, Newtonsoft.Json Add a project reference from your second project to the first
Dependencies should now look like so;
Now within TestConsoleApp, you can add using statements to access the nuget package used in TestConsoleApp2.

QUESTION
TypeError: Cannot read property 'setState' of undefined
This is my code, I saw another question with the same but it was for an earlier version of react and had classes and constructors
initially this.setState was this.state but I changed it due to warnings from VS code
ANSWER
Answered 2020-Nov-30 at 07:54I don't know exactly what you are trying to do.You are trying to update state in a functionnal component as it was a class based component.If you work with functions, the way to provide state is by import the useState hook.From what i've understood in what you're trying to do here is a code that is compatible with using state in functionnal components

QUESTION
Hello I have an app that used now deprecated Camera module in android for displaying the camera view and drawing filters onto it using mlkit face detection. Recently we've decided to upgrade it to CameraX, I did all the necessary steps to make it work as a separate android app and it works. When I want to incorporate it to our existing Custom React Native module no matter what I do, it doesn't show anything on the screen. I've checked the view sizes and they seem to be ok. Below is the code I use to start the camera module.
...ANSWER
Answered 2020-Sep-28 at 10:30The issue happens because the relative layout is not resized after being added to the scene. The workaround is not mine, but I could not find where it was from right now so I'll just leave it here in case someone else is having the similar issue. I solved the issue by calling the layoutHack in the constructor of my RelativeLayout
