I´m reading books about pattern recognision, looking for a way I can detect position and shape of my hand to click. It´s really hard, i made some test but without result, i tried many ideas but ufff nothing

I made some tests with a simple interface based on three squares where if you put your hand in one of them you can make click, click and hold or double click. i tried with google maps and this is the result:Now i have to think how I can fuse them with de particle filter.

I check back the last dirty code of the filter particle, to recheck what was wrong. I spend a week, rewriting the code carefuly and testing. check the results in the next video

well, i already have working the mouse by the particle filter. It´s working well, but it doesn´t rich to the corners well.

well i had made some test using de particle filter to use the mouse, but i couldn't get it work. i'm using functions like mouse_event or sendinput, but can't make it work. i'll still trying for get results.

I tried to make some improvements in the filter, such as the Particle leader stays in the same place while the object doesn't move. it doesn't move, but then I have problems to follow the object movement.

Here you get a video of the progress that I´ve had, at last I managed to finish debug the code and it works pretty well now. At the moment the detection of skin is modified to reduce noise and have a good condition for testing. Under normal conditions there are a lot of noise because of the objects around or simply by lighting among other things.

Does anybody know how can i detect my hand's gesture? orHow can i use the google API in a C program?im looking up for it.

Throwing by chance the particles in a frame, after using the diferential method and having weighted the particles, we choose the particles with a positive value higher than cero and at the minimum of the positions X of the particles and the maximum of the positions Y of the particles we draw the rectangle tracking.

The movement detection using the diferenetial method of the analysis of the movementBy using the filter of particles for the detection of movement with the diferential method I could know if there has been any change in the image.The diferential method is based on taking away two images consecutively in order to know the difference that exists between the two images.I have realised that i can

Skin detection in sequential imageFrom a RGB image, by checking the color of each pixel inside a range we can determine whether is human skin or not. Once the skin is detected a co-ordinated box is drawn through the points from where the skin has been detected. A rectangle is then drawn thanks to a CVR.

I'm working in this week about how draw a rectangle in an image, and make some research about particle filter. I've made some progress on it. i'll post all that in this weekend.

as the program above, this program is just get each frame (or we can say "image") from the video and work as same as a image, converting it to gray sacale or inverts it.color2grayscalevideo.cppNetheros has made a amazing job recognizing the skin color from a video and then highlighting the skin in white and the background in black.skindetector(in spanish but you can watch a video)

I've made a program, as the program before, but this one changes a color image to a gray scale image, and then inverts it.I was thinking about to touch the channels and thinking about how to remove some colors channels and maintain only the gray scale channel. Then a relized that in Opencv there is a function that (work my problem out) (cv.....). thanks to that function we can convert a color

I had many problems with the windows, I couldn't open any window at the beginning but luckily it wasn't the fault of the source code.I wrote "cvNamedWindow" function inside the loop to ensure that if someone closes the window it will open again, and I can keep the window open.

Once upon a time... a program called Wascana (is Eclipse based standalone c++) and a library opencv (Open Computer Vision Library ) that together will keep me busy for a good time.This is the beginning of the end of our lives, jajajja joke.Jokes aside, in this blog I want to talk about my PFC Minority report interfaces for maps navigations.
