imagedesc_generate

PURPOSE

Generate parameters for image or cuboid descriptor.

SYNOPSIS

function imdesc = imagedesc_generate( iscuboid, str_desc, histFLAG, jitterFLAG )

DESCRIPTION

 Generate parameters for image or cuboid descriptor.

 INPUTS
   iscuboid    - 1 for cuboids, 0 for patches
   str_desc    - 'GRAD', 'FB' for images [see descpatch_*.m]
               - 'APR', 'GRAD', 'IMDESC', 'WW', 'FLOW' [see desccuboid_*.m]
   histFLAG    - see imagedesc_ch2desc, also has some additional values [2,3]
   jitterFLAG  - [optional] see jitter_dist, causes everything to be very slow
