Thursday, March 12, 2009. Obtaining filename in C Builder. Sometimes when we are working with image processing, we need to save the resulting image after finishing the process. Therefore we need the image file name so we can use the same file name with the original file with an additional prefix or suffix. Please remember to include map in your program. Std: map int,AnsiString. TFormMain: parseFields( AnsiString filename, AnsiString separator ). Std: map int,AnsiString lFields;. While( 1 ) {. Two days ag...

Thursday, December 31, 2009. Simple Object Tracking using OpenCV. This time, I am showing how to perform a simple object tracking using OpenCV. This is the simplest object tracking based on template matching method, so don't expect too much from this sample. You should be able to develop your own custom algorithm that is more powerful than this to suit your application. Tpl = cvCreateImage(cvSize( TPL WIDTH, TPL HEIGHT ), image- depth, image- nChannels );. Are the size of the search area. If object found...

Mario.Tapilouw: Automatic Threshold
http://mariotapilouw.blogspot.com/2012/04/automatic-threshold.html
Wednesday, April 11, 2012. Threshold plays an important role in image segmentation. The threshold value in an image can be manually or automatically set. Manual threshold is not always suitable for all situation because different image may have different intensity distribution. Zack GW, Rogers WE, Latt SA (1977), "Automatic measurement of sister chromatid exchange frequency", J. Histochem. Cytochem. 25 (7): 741 53, PMID 70454. 1 Declare some IplImage objects:. 2 Load the image from a file:. CvCvtColor(im...

Tuesday, August 04, 2009. Generating sine wave using multimedia timer. In case we need a high resolution timer for our Windows based application, we can use multimedia timer. For an explanation of what multimedia timer is, you can refer to multimedia timer documentation. I will give an example of using this multimedia timer for generating sine wave. First you need to add these two lines in your source code:. Pragma comment(lib, "winmm.lib"). Then after that you can declare an instance of multimedia timer:.

Shows a good tutorial about grabbing image from the webcam and I followed the tutorial. It is based on OpenCV and I used Visual C 2005 to write the program. Here's what I got:. Hehehe. this is just the beginning, wait for my other projects :D. Posted by mario at 3:59 PM. Friday, September 11, 2009. Real Time chart using OpenCV. CvInitFo...

Mario.Tapilouw: Sine Fitting
http://mariotapilouw.blogspot.com/2012/03/sine-fitting.html
Saturday, March 03, 2012. Sine is not a linear function, but fitting series of data to sine function is actually not a difficult task. I need to apply this fitting function so I was trying to find a way to do this. Sine function can be represented in general form as:. Y(x) = A C * sin(x b). This function can be rewritten as:. Y(x) = A C * sin(b) * cos(x) C * cos(b) * sin(x). Or can also be written as:. Y = b0 b1 * x1 b2 * x2. 2 b1 2 b2 2 = c 2 * (sin 2(b) cos 2(b) = c 2. B1 2 b2 2. 3 tan(b) = b1/b2.

Mario.Tapilouw: Multiple Webcam using OpenCV 2.1 and Visual Studio 2008
http://mariotapilouw.blogspot.com/2011/12/multiple-webcam-using-opencv-21-and.html
Thursday, December 08, 2011. Multiple Webcam using OpenCV 2.1 and Visual Studio 2008. I just found out that it is not difficult to connect to two webcam using OpenCV and do image processing on the captured images. I used OpenCV 2.1 and Visual C 2008 for this program, so those who are familiar with Visual C 2008 should be familiar with this code. The installation and configuration of OpenCV is explained clearly in their wiki. And you can follow the steps written there. Int w = 640;. Int h = 480;. CvShowIm...

Thursday, February 26, 2009. Writing a well-written code is faster than debugging a badly written code. Debugging is a pain in the ass. It can make you sleepless in the evening, lose your mood in the morning, decrease your appetite, and even a nightmare, hahaha. This is the most efficient way to develop a software, trust me hehe.
