What is MatchIT?
●
●
MatchIT is a unique new system for the
inspection of multicolored, patterned, and
textured materials.
Designed with advanced digital imaging
technology, MatchIT is ideal for measuring
and controlling the appearance of natural and
man-made multicolored objects of all sorts.
Why Is MatchIT Important?
●
●
●
MatchIT can automatically image, inspect,
and monitor the appearance of objects that
were previously unmeasureable!
MatchIT examines colors and textures –
often the most critical characteristics of
consumer products
MatchIT judges objects objectively, faster
and more accurately than human inspectors
Traditional monochrome
inspection
Color appearance analysis
What Can MatchIT Do?
●
Accurately match samples based upon color
and texture patterns
●
Classify, grade, and sort
●
Verify product appearance
●
Find defects
●
Assess visual similarity
ALL WITHOUT ANY PROGRAMMING!
What Does MatchIT Consist of?
MatchIT systems include a color video
camera, illumination unit, PC, and special
image analysis software. Configurations are
available for online and offline inspection
tasks and microscopy applications.
How Does MatchIT Work?
●
●
●
MatchIT is trained, much like a human, to
recognize patterns of colors and textures.
References (single or averaged) are stored
for comparison to new images.
Image analysis uses pattern matching and
true-color processing
Calibration and supervised learning ensure
robust performance
Matching Colors
●
●
●
Matching occurs in
a 3D color space
(RGB, HSI, or LAB)
Inspect complex
and irregular color
patterns
Results are
independent of
sample orientation,
spatial patterns,
and image
complexity
Matching Textures
●
●
●
●
Involves the spatial
arrangement of colors and
intensities
Handles homogeneous and
non-homogeneous textures
Operates in either grayscale or
color texture mode
Defects detected using color
and/or texture
The relative importance of color vs. texture is user-definable!
MatchIT Applications
Control or Sort Mixtures of Colors
and Patterns
●
●
●
Cereal inspection
Manufacturing
process control
Natural products
Achieve accurate
product mix by color
Find Defects in Color Texture
Patterns
●
●
●
Fabric inspection
Do you see the color defect on the right side?
Not possible with
grayscale processing
Manual review may
miss subtle color and
texture changes
Specific defect types
may be trained and
located
Grade Products
●
●
Quantify variation
●
Rank order samples
●
Leather inspection
Grading based on
color and texture
Agrees with human
visual perception
Analyze Texture
●
●
●
Ensure
homogeneity and
percent coverage
Measure surface
roughness
Correlate visual
with physical
texture
Cement inspection
MatchIT Software

MatchIT in Action
●
●
Objective:
Locate defect(s)
in textured
material
Challenge:
Defects may be
subtle variations
in color and/or
texture, within a
highly textured
image
Note the two
defects

MatchIT Calibration
●
●
Color target
Color calibration
ensures
repeatable results
despite changes in
illumination and/or
image capture
