This activity is a demonstration on how to restore an image which is corrupted with a known degradation function such as motion blur and additive noise. The image degradation and restoration process can be modeled by the diagram shown below.

Wednesday, September 23, 2009. A grayscale image were selected and processed using Scilab. The parameter a, b and T was varied to see the their effects to the degraded image. The degraded images are shown in Figure 1.

Thursday, September 24, 2009. Activity 19 - Restoration of Blurred Image. This last activity is about demonstration of restoration of a corrupted grayscale image with a known degradation function which in this case is motion blur and additive noise using Weiner filtering. The following schematic diagram is a model of the image degradation and restoration process.

Monday, October 12, 2009. Activity 19 - Restoration of Blurred Image. The uniform linear motion causing this blurring can help model and provide a basis of removing motion blur in images. Is the object image, and g. Is the blurred image, the blurring is attributed to a uniform linear motion along x and y, namely x o. Where G and F represents the Fourier transform of the blurred and original image. H is the motion blur transfer function, with x o. Using the description of the motion bl.

Monday, October 12, 2009. ACTIVITY 19 Restoration of Blurred Image. The following are the investigations I did in relation to the degradation and restoration of the image shown in Figure 1.

Sunday, October 11, 2009. In this activity, we restore a motion blurred image with Gaussian noise using a Weiner filter and a pseudo Weiner filter. In the Fourier space, the degraded image is given by. Where G is the degraded image, F is the original image, N is the noise, H is the transfer function given by. Where T is the duration of exposure, a and b represents displacements along u and v respectively. Where K is a constant.
