Detailed Description

Class implementing the locally uniform comparison image descriptor, described in [206].

An image descriptor that can be computed very fast, while being about as robust as, for example, SURF or BRIEF.

Note: It requires a color image as input.

static

Parameters

lucid_kernel	kernel for descriptor construction, where 1=3x3, 2=5x5, 3=7x7 and so forth
blur_kernel	kernel for blurring image prior to descriptor construction, where 1=3x3, 2=5x5, 3=7x7 and so forth
