features.isContionous() assertion - clustering - opencv

probably you forget to initialize the mat in hierarchical clustering.

region of interest (ROI) opencv

they have changed how ROI works in opencv
if you'd like to focus on a region in an image you need to copy it to another image/mat

Mat samples_hog = samples( Rect(0, 0, 96, soFar)).clone();

and do not forget the .clone() part it is important.

in Rect with four parameters (x, y, width, height) but not (x1, y1, x2, y2)

no highlighting in vim

:noh

how tu submit opencv jobs to sge (sun grid engine)

here is the script that I use to submit opencv jobs on sge

qsub -v LD_LIBRARY_PATH=$LD_LIBRARY_PATH:<opencvPATH>/lib/ -b y -cwd -l mem_free=4g -l mem_token=4g ./FlannMatch <PARAMETERS>

matlab figure fonts issue in ubuntu

it seems like matlab figure fonts are not changed even if you make the changes on ubuntu.

you need to install packages;
xfonts-75dpi
xfonts-100dpi

undeclared variable in flann/lsh_table.h with -std=gnu++0x (Bug #2179)

if you faced with a problem like this;

/usr/local/opencv/include/opencv2/flann/lsh_index.h:49:0,

                 from /usr/local/opencv/include/opencv2/flann/all_indices.h:42,

                 from /usr/local/opencv/include/opencv2/flann/flann_base.hpp:44,

                 from /usr/local/opencv/include/opencv2/flann/flann.hpp:50,

                 from /usr/local/opencv/include/opencv/cv.h:69,

                 from FlannMatchWindows.cpp:7:

/usr/local/opencv/include/opencv2/flann/lsh_table.h: In member function ‘void cvflann::lsh::LshTable<ElementType>::add(cvflann::Matrix<T>)’:

/usr/local/opencv/include/opencv2/flann/lsh_table.h:196:14: error: ‘use_speed_’ was not declared in this scope

this then you can check this link out and even though they do not say the fix you can find it here;

remove the statement "if (!use_speed_)"  from the line 196 lsh_table.h

it is also fixed on later version of 2.4.2
