In this paper, a morphological approach based on pixel connectivity is proposed for removing impulse noise in images. Impulse noise, also called the salt and pepper noise, usually occurs in dark and bright regions of the image and the presence of this noise degrades the visual quality of the image by affecting its texture and fine details. Our algorithm(More)
The Fast Fourier transform (FFT) is an important operation in digital signal processing applications. In applications such as biomedical signal processing, the signals are real. The real-valued signals exhibit conjugate symmetry, giving rise to redundant values in the outputs. This property can be exploited to reduce arithmetic computations, area and power(More)
