depth

By using Kinect, I can get depth image in which each depth image pixel store the distance(in millimeter) between camera and object. Now I want to save them so that I can use later. What is the best recommendation? I am thinking to save the depth image as an image (jpg/png, etc). However, the value is usually from 50 mm to 10000 mm while the normal image element can store from 0-255. Then I will need to scale the data to range 0-255 and that may exploit the data somehow. You can use any format like tiff or png that supports 16 bit grayscale images, since your data will fit in a 16 bit (2^16-1

I want to get the current depth buffer to a texture, to access it in a shader. For various reasons I can't do a separate depth pass, but would need to copy the already-rendered depth. glReadPixels would involve the CPU and potentially kill performance, and as far as I know glBlitFramebuffer can't blit depth-to-color, only depth-to-depth. How to do this on the GPU? The modern way of doing this would be to use a FBO. Attach a color and depth texture to it, render, then disable the FBO and use the textures as inputs to a shader that will render to the default framebuffer. All the details you need

I'm working with Kinect and OpenCV. I already search in this forum but I didn't find anything like my problem. I keep the raw depth data from Kinect (16 bit), I store it in a CvMat* and then I pass it to the cvGetImage to create an IplImage* from it: CvMat* depthMetersMat = cvCreateMat( 480, 640, CV_16UC1 ); [...] cvGetImage(depthMetersMat,temp); But now I need to work on this image in order to do cvThreshdold and find contours. These 2 functions need an 8-bit-depth-image in input. How can I convert the CvMat* depthMetersMat in an 8-bit-depth-CvMat* ? The answer that @SSteve gave almost did

Based on this question asked by @ben75: Android : save a Bitmap to bmp file format My question now is: How can I have a BMP image with the depth of 1 bit per pixel (Black & White)? Answering my own question... After some tough search all over the web I realized I had to create 2 things: a bitmap black and white - and did that using the approach of making all 0's for colors below 128 and 255's for the rest, like this (this is C# code, as I'm using Xamarin to code my app): private void ConvertArgbToOneColor (Bitmap bmpOriginal, int width, int height){ int pixel; int k = 0; int B=0,G=0,R=0; try{

I noticed, while trying to draw large numbers of circles, that occasionally, there would be some kind of visual bug where some circles wouldn't draw properly. Well, I narrowed it down, and have noticed that if there is 23 or more objects with 00 for an alpha value on the same spot, then the objects below don't draw. It appears to be on a pixel-by-pixel basis, since parts of the image still draw. Originally, this problem was noticed with a class that inherited Sprite. It was confirmed to also be a problem with Sprites, and now Bitmaps, too. If anyone can find a lower-level class than Bitmap
