IMPULSE DETECTION BY ENTROPY DETECTOR (H-DETECTOR)
This paper presents the use of a new entropy
impulse detector (H - detector). The impulse noise
removing methods are well known. The median filter
is the most widely used. Thus, the image is
filtered point by point and in many applications
the filter itself introduces blurring, which may be
more objectionable than the original noise.
Consequently, approaches to identification of the
impulse noise were developed. A new detector is
compared with different methods. The performance of
the proposed method is evaluated through subjective
and objective criteria.
