Hi everybody. I'm developing an augmented reality application for Android that uses the phone's camera to recognise the arrangement of the coloured squares on each face of a Rubik's Cube. One thing that I am unsure about is how exactly I would go about detecting and recognising the coloured squares on each face of the cube. If you look...
Hello, I am trying to make a C# desktop application (with Emgu CV wrapper) which captures the feed from the camera, detects edges in the feed and then displays the original feed (coloured) with the edges - so somewhat of a combined coloured feed and edges. I successfully get the feed from the camera. I also detect the edges in the feed ...
Hi there I'm interested about the computer vision field. Which are the must read journals in this field? Which are the big names of this field (conferences, blogs, peoples, libs). thank you :) ...
Can anybody provide simple steps of "Skeleton Pruning by Contour Partitioning with Discrete Curve Evolution" Algorithm or c++ code i have document if some one is familiar simple steps of the algorithm ...
I am working with some code which outputs a 3x3 rotation matrix and a translation vector representing a cameras orientation and location. However, the documentation states that to get the location of the camera one must multiply the transposed and inverted rotation matrix by the translation vector. Does that mean that the original vect...
I have a simple photograph that may or may not include a logo image. I'm trying to identify whether a picture includes the logo shape or not. The logo (rectangular shape with a few extra features) could be of various sizes and could have multiple occurrences. I'd like to use Computer Vision techniques to identify the location of these...
I am looking for papers/algorithms for merging projected textures onto geometry. To be more specific, given a set of fully calibrated cameras/photographs and geometry, how can we define a metric for choosing which photograph should be used to texture a given patch of the geometry. I can think of a few attributes one may seek minimize i...
i am trying to implement discrete curve evolution algorithm in c++ do any one help me with psudo code or c code or some simple steps of your understanding ...
From Wikipedia, camera resectioning is the process of finding the true parameters of the camera that produced a given photograph or video. Camera resectioning is also known as geometric camera calibration. Currently I am using Camera Calibration Toolbox for Matlab for my camera calibration. The toolbox returns calibration parameters suc...
I am starting out as an Android Developer, and I would like to know if there are any Computer vision libraries or Augmented Reality libraries for the Android SDK, as I am planning to use these libraries for a mobile app. I have read that if I download the NDK, I might be able to "import/use" the C openCV, and ARtoolkit libraries, but I ...
We have an application, where we get a message from an external system and then we take a picture, do some processing and return something back to the external system. Doing some performance testing, I found two problems (they are somewhat related). I was hoping someone will be able to explain this to me. 1) Does _capture.QueryFrame() b...
I'm trying to reconstruct 3D points from 2D image correspondences. My camera is calibrated. The test images are of a checkered cube and correspondences are hand picked. Radial distortion is removed. After triangulation the construction seems to be wrong however. The X and Y values seem to be correct, but the Z values are about the same a...
So I have real time video stream. With 1 (one) person on It . It Is Black and White, I need to be able to capture this persons eyes and mouth (direction (at least X,Y), state (at least opened or closed) ) So Is there any fast library(s) for finding human eyes and mouth in Flash in such case? (pure Actionscript or Haxe\Java\C++\C port in...
I want to recognize the shapes in the picture by template matching.Is the "ExhaustiveTemplateMatching" is the right option given in Aforge.Net for this purpose.Had anyone tried this class and find it working correctly.How accurate and right choice this class is for achieving my purpose.Suggest any other methods or Alogrithms as well for ...
I'm currently an undergrad in computer science and I'll be entering my final year next year. Augmented reality is something I find to be a really interesting topic, but I have no idea where to start learning about it. Where do you start learning about this topic and what libraries are available? ...
so, let's say i have the long/lat or address of many buildings can get satellite images, "street view", and perhaps 3d/perspective views of buildings. want to find: height, number of floors, floor area (max building footprint) of the building. about 200k buildings. Is there a library for recognizing buildings from satellite shots o...
I'm trying to auto-detect the axis of rotation on a 3d pointcloud. In other words, if I took a small 3d pointcloud, chose a single axis of rotation, and make several copies of the points at different rotation angles, then I get a larger pointcloud. The input to my algorithm is the larger pointcloud, and the desired output is the sing...
Hello: I would like to do an interesting project for a computer graphics course. I know that there is a lot of literature out there (i.e. SIGGRAPH conference papers). I have a very large range of interest with regard to computer graphics (i.e. image processing, 3D modeling, rendering, animation). However, I've only taken computer vision...
