Had the error when called the 'edge' function in such manner:
octave:55> gcb=edge (ifile,'Canny',[0 7], 1.6);
The error trace:
error: `len' undefined near line 367 column 54
error: evaluating binary operator `==' near line 367, column 74
error: evaluating binary operator `&&' near line 367, column 51
error: if: error evaluating conditional expression
error: evaluating if command near line 365, column 7
error: evaluating switch command near line 165, column 3
error: called from `edge' in file
`/usr/share/octave/packages/image-1.0.6/edge.m'
error: evaluating assignment expression near line 55, column 4
Fixed the typo in edge.m, line 367 by changing "len" to "length"
