Title:
SEPARATION FILTER DECIDING DEVICE AND TIRE INSPECTING DEVICE
Document Type and Number:
WIPO Patent Application WO/2008/050686
Kind Code:
A1
Abstract:
A separation filter deciding device provided with an image input unit, a memory unit,
a setting unit, an evaluating unit and a separation filter deciding unit is disclosed.
The image input unit inputs a picked-up image in which a tire surface including
a characteristic portion is picked up. The memory unit stores a plurality of
filters to carry out image processing for the picked-up image, a teacher image in
which the characteristic portion is separated from the picked-up image and a
weighted image in which a weight is set to a predetermined region for the picked-up image.
The setting unit sets a separate filter combined with two or more filters out
of the plurality of the filters. The evaluating unit seeks an evaluating value
on the basis of an image formed by adding the weight based on the weighted image
to a difference between the processed image subjected to processing by each of
the separate filters and the teacher image. The separation filter deciding unit
makes the setting of the setting unit and the arithmetic operation of the evaluation
unit repeat until the evaluating value is in a predetermined range and decides
that the separate filter corresponding to the evaluating value as a result of
the repetition is a separation filter to separate the characteristic portion
from the picked-up image.
