2015-07-09 10:42:52 -0600 | commented question | My LBP face detection does not detect anything, never Update! I started to work again on this project after a compelling job. I tried to save Mat s in files as per: imwrite("test1.ppm", frame); imwrite("test2.ppm", equalized); but the saved files have width 0! So I think the problem is transforming my UYVY image into an OpenCV frame. I haven't compiled OpenCV with PNG nor JPEG support so I tried to save them as PPM, but for the same reason is it possible that imdecode (see example above) fails for UYVY? Do I need to recompile OpenCV with some support? Some cmake flag enabled? And in this case, which one? |

2015-06-03 06:20:41 -0600 | asked a question | My LBP face detection does not detect anything, never Hi to all, I'm a beginner with OpenCV. A real beginner, I'm at my first real application. I'm setting up OpenCV for face detection on an embedded device; the face detection will occur an image at a time, image are fed from an external source. I have read a lot of guides and tutorials, wanting to statically link libs, so I recompiled OpenCV 2.4.11 and finally did it (flags were ALL unchecked apart BUILD_opencv_[calib3d, contrib, core, features2d, flann, gpu, highgui, improc, legacy, ml, nonfree, objdetect, ocl, photo, stitching, superres, ts, video, videostab] and ENABLE_OMIT_FRAME_POINTER; I set CMAKE_BUILD_TYPE to "Release" too). Now I can compile and run my application using "-lopencv_oobjdetect -lopencv_imgproc -lopencv_highgui -lopencv_core -lrt -lz -lm" as linker flags. My code is: I redirected stdout and stderr to two files but they stay empty, it seems to work like a charm, but nothing is ever detected. I tried, in many steps, to pass to the above code 1 to 30 images per second, without any errors/complains/exceptions/(other things I don't know what to expect in my noobiness). Any ideas, suggestions, tutorial that I should have read and I missed? TIA, Ivan |
