2017-07-03 06:22:27 -0600 | asked a question | build opencv 2.4.9 with gstream hi everybody i want to compile opencv with gstreamer i read http://answers.opencv.org/question/65... and i did just fallow steps: Download pkg-config-lite-0.28-1_bin-win32 Add following system paths C:\Program Files (x86)\pkg-config-lite-0.28-1\bin C:\Gstreamer\1.0\x86_64\lib\gstreamer-1.0 C:\Gstreamer\1.0\x86_64\lib Add Environment Variable PKG_CONFIG_PATH C:\Gstreamer\1.0\x86_64\lib\pkgconfig Edit opencv\sources\CMakeLists.txt ... OCV_OPTION(WITH_GSTREAMER "Include Gstreamer support" ON IF (WIN32 OR UNIX AND NOT ANDROID) ) but gstreamer still is no please please help me i add below code to LBPH::train(InputArrayOfArrays _in_src, InputArray _in_labels, bool preserveData)
after produced the mat lbp_image (in opencv source)
static int uniform[256] = // for exactly 8 bits / neighbours !
{ then also the number of histogram bins from 256 to 59 like below : but i got this error : assertion failed : (lutcn == cn || lutcn == 1) && lut.total() == 256 && lut.isContinuous() && (src.depth() == CV_8U || src.depth() == CV_8S) in function LUT i know that problem is in : src.depth() == CV_8U || src.depth() == CV_8S) please help me in detail that what changes are need, im a begginer in opencv i have a qt program that using opencv i can cross compile qt programs and run on raspberry but i ...

2017-04-21 23:33:04 -0600 | commented question | idea about difference bet moving red obj & fire hsv is better or rgb or ycrcb? im using: colorDetect(RGB based)+svm.predict if i add red moving obj to negative,true alarms reduced |
2017-04-18 07:05:11 -0600 | asked a question | idea about difference bet moving red obj & fire the subject is clear friends, i can detect fire very good by svm, but when i add negative sample about moving red obj, again in the test step , a moving red object detected as fire!! |

2017-04-08 03:02:53 -0600 | asked a question | best methods for fire detection best methods for fire detection using image processing?
i saw svm,and color based (hsv or ycrcb) methods,
i don't have 2000 negative and positive sample to train svm and see its result, so i hope someone guide me
that this method is ok or not?
note that im not a researcher,im just working on open source codes |

2017-03-13 00:58:24 -0600 | asked a question | accuracy of uniform lbp is scandal hi, im using opencv func for uniform lbp (LUT ) and accuracy of recognition get worth but i read that this will not happen,what am i wrong? read images resize each image lut(images,lookup table,images); train images detection |
2017-03-11 05:50:49 -0600 | commented answer | uniform lbp using lut Func. @berak i changed my code to your suggestion,my trained model reduced from 6,7 Mb to 6,3 and accuracy is scandal!!!! why? |
