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?
industrial approach of speed control of dc series motor
Q. Three single-phase 100-kVA, 2400:240-V, 60-Hz transformers (each ofwhich has an equivalent series impedance of 0.045+j0.16 referred to its low-voltage side) are connected to fo

The goal of this project is to model a system and to design a controller for the system so that the closed-loop system performs satisfactorily.
For the network shown in Figure, find the current in each resistor by means of nodal analysis.
