In this problem use the Lena image shown in Figure 2.23

In this problem use the Lena image shown in Figure 2.23 which is available in the book toolbox.

Load the Lena image in MATLAB and display using the imshow function.

Consider the 1D impulse response h [ n ] = 1 {1, 1, 1, 1, 1}. Using it perform 1D 5 ↑ convolution along each row of the Lena image and display the resulting blurred image. Comment on the result.

Using the above impulse response now perform comvolution along each column of the Lena image and display the resulting blurred image. Compare this image with the one in part (b).

Using h [ n ] perform convolution along each column of the result image of part (b) and display the resulting image. How does it compare with the above two result images as well as the one in part (c) in Problem 15?

Done, so where do i send my answers to? all joking aside where are you having issues with and what have you done so far?

I don't believe this forum is a place to get people to do your homework for you ...

Perhaps if you could ask a specific question regarding what you don't understand, then someone can answer that.
