Filtering
(i) Write an m-file "mymedian.m" which will take an image and filter size and perform median filtering. Display input and output image. Use
help median
function imm=mymedian(imn,msize) [h w]=size(imn); kernel_size=? imm=imn; for i=msize+1:(h-msize) for j=msize+1:(w-msize) imm(i,j)=median(reshape(imn(i-msize:i+msize,j-msize:j+msize),1,kernel_size)); end end
What is the median value of an image?
Comment on the complexity (number of operations per pixel) of the algorithm.
(ii) Write an m-file "mygaussian.m" which will take an image and filter size and perform Gaussian filtering. Display input and output image.
function img=mygaussian(imn,sigma) g=gauss(sigma);
img=?(iii) Perform median and Gaussian filtering on face_g.png, face_m.png,statue_m.png. What kind of noise the median filer is useful for? What kind of noise the Gaussian filer is useful for?

Define Cables - Generation and Absorption of Reactive Power? It is well known that the shunt capacitance of the cable is very large as compared to that of an overhead line. Thi
Q. What is Barkhausen criterion? Why is the value of Ab kept slightly greater than 1? The condition |Ab| = 1 is called the Barkhausen criterion. It implies that when |Ab| = 1,
Q. What is transconductance? Explain its significance from the transfer characteristics. Transconductance is the transistor gain of the JFET; it indicates the amount of control
NOR Gate NOR means NOT OR . it complements the output of an OR gate. The symbol of Nor gate in fig. (a) shows that a Nor gate comprises of an OR gate followed by a N
