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?
PNP The other kind of BJT is the PNP with the letters "P" and "N" standing for the majority charge carriers inside the dissimilar regions of the transistor. Figure:
Q. Draw a 100 line exchange using two motion selectors and elucidate, how switching takes place in it. Ans: In a 100 line exchange, every subscriber is assigned a 2 digit
Mode 1 ( 0 By applying a positive output pulse of the pulse width modulator to the transistor Q 1 it gets turned on. An input current in flows through V in Q 1

What do you mean by Bezier curve? Shown B0 (1,1), B1 (2,3), B2 (4,3), B3 (3,1) the vertices of Bezier polygon, calculate seven points on Bezier curve. Write in brief the differe
Q. What are the different types of coupling in amplifiers? The coupling between stages of amplifications may also be used to classify amplifiers. There are four main groups: di

Depletion type MOSFET The channel is of silicon. It can be two type of channel that is an n-type or p-type channel; it is still mostly silicon. After that, we take note that
A 3-phase, wye-connected, 11.8 kV, 100 MVA turbo- generator of 0.8 power factor lagging has a synchronous reactance of 2.0 p.u. on rating. The generator is driven by a steam turbin
The aim of this project is to design, construct and build a motorised base driven by two small dc motors. The motor drives are two H-bridges. The switching devices in these bridges
