Kinect Facial Recognition and Training Images -

i using this facial recognition program kinect

the problem need able register , keep images training database. whenever run it, program works , able detect , recognize faces images not kept. code needs changed?

i need on appreciated.

}

if trying save images folder, this:

        ...          if (this.taketrainingimage)         {             this.targetfaces.add(new bitmapsourcetargetface             {                 image = (bitmap)face.grayface.clone(),                 key = this.namefield.text             });              //save image             jpegbitmapencoder encoder = new jpegbitmapencoder();             bitmapframe outputframe = bitmapframe.create(loadbitmap(e.processedbitmap));             encoder.frames.add(face.grayface);             encoder.qualitylevel = 96dpi;              using (filestream file = file.openwrite("c://users//your name//documents//face trainer//images//face " + targetfaces.count + ".jpg"))             {                 encoder.save(file);             }              this.taketrainingimage = false;             this.namefield.text = this.namefield.text.replace(this.targetfaces.count.tostring(), (this.targetfaces.count + 1).tostring());              if (this.targetfaces.count > 1)                 this.engine.settargetfaces(this.targetfaces);         }          .... 

then load files...

string[] files = system.io.directory.getfiles("c://users//your name//documents//face trainer//images//"); bitmap[] images = new bitmap[files.length];  (int = 0; < files.length; i++) {     images[i] = (bitmap) image.fromfile(file, true); } 

if trying add images database, follow this tutorial.

i recommend saving images file since beginning, , using databases requires more work. however, when more experienced databases effective @ sort of thing. luck!:)
