Package: octave-image Version: 1.0.8-3+b1 Severity: normal
Whenever imtophat is called with parameters that pass its parameter validation, and it attempts to perform the actual top-hat filtering operation, it attempts to access undefined variable and causes an error. Test code: test.m: I = [1 1 1; 1 1 1; 1 1 1;]; se = [1 1; 0 1;]; imtophat(I, se) Execution: % octave test.m Actual output: error: `SE' undefined near line 33 column 29 error: evaluating argument list element number 2 error: evaluating prefix operator `!' near line 33, column 17 error: evaluating binary operator `&' near line 33, column 15 error: evaluating assignment expression near line 33, column 10 error: called from `imtophat' in file `/usr/share/octave/packages/3.0/image-1.0.8/imtophat.m' error: near line 3 of file `test.m' Expected output: ans = 0 0 1 0 0 1 1 1 1 Analysis: It appears that the imopen call in /usr/share/octave/packages/3.0/image-1.0.8/imtophat.m erroneously refers to 'SE' when it should refer to 'se'. How this could ever have worked, I don't know. Perhaps Octave was case-insensitive in the past? -- System Information: Debian Release: squeeze/sid APT prefers testing APT policy: (500, 'testing') Architecture: i386 (i686) Kernel: Linux 2.6.28.7pryan (SMP w/2 CPU cores) Locale: LANG=en_US, lc_ctype=fi...@euro (charmap=ISO-8859-15) Shell: /bin/sh linked to /bin/bash Versions of packages octave-image depends on: ii imagemagick 7:6.3.7.9.dfsg2-1 image manipulation programs ii libatlas3gf-base [libl 3.6.0-24 Automatically Tuned Linear Algebra ii libatlas3gf-sse2 [libl 3.6.0-24 Automatically Tuned Linear Algebra ii libblas3gf [libblas.so 1.2-2 Basic Linear Algebra Subroutines 3 ii libc6 2.9-25 GNU C Library: Shared libraries ii libfftw3-3 3.1.2-3.1 library for computing Fast Fourier ii libgcc1 1:4.3.3-3 GCC support library ii libgfortran3 4.3.3-3 Runtime library for GNU Fortran ap ii libhdf5-serial-1.8.3 [ 1.8.3-2.1 Hierarchical Data Format 5 (HDF5) ii libjpeg62 6b-14 The Independent JPEG Group's JPEG ii liblapack3gf [liblapac 3.1.1-6 library of linear algebra routines ii libncurses5 5.7+20090228-1 shared libraries for terminal hand ii libpng12-0 1.2.35-1 PNG library - runtime ii libreadline5 5.2-4 GNU readline and history libraries ii libstdc++6 4.3.3-3 The GNU Standard C++ Library v3 ii octave3.0 1:3.0.5-7 GNU Octave language for numerical ii zlib1g 1:1.2.3.3.dfsg-12 compression library - runtime octave-image recommends no packages. octave-image suggests no packages. -- no debconf information -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
