Can you explain above paragraph? Thank you in advance !

2013-03-13 04:18:05 -0500 commented answer Is there any programs to recognize objects?

Thanks a lot dear friend I didn't see the links since now but I will read them soon . My purpose is that I want to describe some objects for program (like car, tree , street lights ,etc) and when the camera see those (in every directions) the program can recognize them .

I think I understand whole of solution but I must read more about details and I think building the template models should be my approach , but i am not sure!

And also i couldn't understand your mean in this paragraph :

Some of these techniques depend on a large set of labeled images, assigning a class, then defining the nearest example to the new test image and feeding it the same label. Other techniques use tons of positive and negative object sampels to create a abstract model of how the item should look like.

2013-03-13 01:55:57 -0500 asked a question Is there any programs to recognize objects?

HI

IS there any programs that can recognizing objects? I mean after a car was in front of the camera the program says car or after a bird did it , it says bird .

Also I want to know what is the name of this field of image processing or i can search what WORDs or PHRASEs for find more information or instruction for it?

Thanks a lot

hi

i want to configure opencv2.3.1 that i have installed from ubuntu software center and the headers are in usr/include/opencv and the libraries are in usr/lib . i tried many ways and instructions but still i havent desired result.
