Note OpenCV offers support for the image formats Windows bitmap (bmp), portable image formats (pbm, pgm, ppm) and Sun raster (sr, ras). With help of plugins (you need to specify to use them if you build yourself the library, nevertheless in the packages we ship present by default) you may also load image formats like JPEG (jpeg, jpg, jpe), JPEG 2000 (jp2 - codenamed in the CMake as Jasper.

I am using Mac and code run through Eclipse C/C++ by including its libraries in project

Opencv Eclipse C++ Linux

I get it, but how do you install opencv on your machine? Do you compile it or get binary from site?
