— There are many applications in image analysis where
it is important to detect accurately patterns that include color
and texture, e.g., plastic or concrete traffic barriers. This paper
proposes a new method and extends a general machine vision
approach for on-line pattern detection using color and textural
information. Our proposed method includes the following steps:
division of each image into sub-images, use of the Haralick and
Binary Quaternion-Moment-Preserving methods to extract
texture and color features, support vector machines for
classification, and a post processing stage using clustering. The
method was tested in two databases. The first one with three
pattern types and the results yielded a detection rate of 96.4%
with 14 false positives. The second database has nine pattern
types and the results yielded a detection rate of 98.4% with 9
false positives. The results were compared advantageously with
Haralick and BQMP methods separately.
