Kinect Depth and Image Frames Alignment

由 人走茶凉 提交于 2019-11-29 04:17:10
I am playing around with new Kinect SDK v1.0.3.190. (other related questions in stackoverflow are on previous sdk of kinect) I get depth and color streams from Kinect. As the depth and RGB streams are captured with different sensors there is a misalignment between two frames as can be seen below. Only RGB Only Depth Depth & RGB I need to align them and there is a function named MapDepthToColorImagePoint exactly for this purpose. However it doesn't seem to work. here is a equally blended (depth and mapped color) result below which is created with the following code Parallel.For(0, this

Reducing color depth in an image is not reducin the file size?

问题 I use this code to reduce the depth of an image: public void ApplyDecreaseColourDepth(int offset) { int A, R, G, B; Color pixelColor; for (int y = 0; y < bitmapImage.Height; y++) { for (int x = 0; x < bitmapImage.Width; x++) { pixelColor = bitmapImage.GetPixel(x, y); A = pixelColor.A; R = ((pixelColor.R + (offset / 2)) - ((pixelColor.R + (offset / 2)) % offset) - 1); if (R < 0) { R = 0; } G = ((pixelColor.G + (offset / 2)) - ((pixelColor.G + (offset / 2)) % offset) - 1); if (G < 0) { G = 0; }

How to capture depth data from camera in iOS 11 and Swift 4?

I'm trying to get depth data from the camera in iOS 11 with AVDepthData, tho when I setup a photoOutput with the AVCapturePhotoCaptureDelegate the photo.depthData is nil. So I tried setting up the AVCaptureDepthDataOutputDelegate with a AVCaptureDepthDataOutput, tho I don't know how to capture the depth photo? Has anyone ever got an image from AVDepthData? Edit: Here's the code I tried: // delegates: AVCapturePhotoCaptureDelegate & AVCaptureDepthDataOutputDelegate @IBOutlet var image_view: UIImageView! @IBOutlet var capture_button: UIButton! var captureSession: AVCaptureSession? var

How can I check the color depth of a Bitmap?

I'm working on an application that prints a folder of image files, including JPEG and TIFF. The TIFF images are usually Black and White (1bpp). After loading the image, I want to determine if the image is Color or B&W or Grayscale so I can send the image to the right printer (color printer or black and white printer). I'm using the Bitmap constructor image = new Bitmap(filename); to load the image. EDIT: The answer to check the pixel depth is great for B&W. Any ideas on checking if the image is grayscale without iterating through every pixel? The proper way to check this is: For JPEG files you
