Wooden bridge.

(brg1)

The original image.

(brg1blu1)

Non-ideal optical transfer function (OTF) image simulated by multiplying the Fourier Transform of brg1 with the Fourier Transform of a Gaussian image with standard deviation = 5.

(brg1dec1)

Result obtained by dividing the Fourier Transform of brg1blu1 by the Fourier Transform of the Gaussian blurring kernel.

(brg1blu2)

Result of adding 0.1% salt and pepper noise to brg1blu1.

(brg1dec2)

Result obtained by dividing the Fourier Transform of brg1blu2 by the Fourier Transform of the Gaussian blurring kernel.

(brg1dec3)

Result obtained by dividing the Fourier Transform of brg1blu2 by the Fourier Transform of the Gaussian blurring kernel and ignoring values of the OTC which fall below a threshold of 3.

(brg1blu3)

Non-ideal optical transfer function (OTF) image simulated by convolving brg1 with a spatial domain Gaussian image with standard deviation = 5.

(brg1dec4)

Result obtained by dividing the Fourier Transform of brg1blu3 by the Fourier Transform of the Gaussian blurring kernel.

(brg1dec5)

Result obtained by dividing the Fourier Transform of brg1blu3 by the Fourier Transform of the Gaussian blurring kernel and ignoring values of the OTC which fall below a threshold of 5.
