Methods based on some image processing techniques are
proposed in this paper for the classification of various
defects on rice kernels. The methods are computationally
simple and extract features representing defects on rice
kernels in an efficient way. This fact is evident from the test
result. The same methods can be used for defect detection
on any class of rice samples. Color image processing can
distinguish between the dead and damaged rice kernels.
Immature kernels can also be detected by estimating the
width to length ratio of the rice seed, which has not been
implemented here. As the computational complexity is less
so the proposed method can also be used in real life for
defect detection in rice samples.
