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?
(a) Which one of the four digital-to-analog conversion techniques (ASK, FSK, PSK or QAM) is most susceptible to noise? Explain your answer. (b) Given the bit pattern 01001110,
Lead Acid Accumulators : These are the most common storage batteries which can deliver a heavy current when short-circuited. There are also many other hazards with these accumulat
Draw the hysteresis loop for a soft magnetic material and compare it with the hysteresis loop of hard magnetic material. Give two examples of each. Soft and hard magnetic mate
what is 2 bit counter?
Thermal noise This is the most significant noise in an ampli?er. It is produced by random movements of electrons in the resistors. This is caused by the ?uctuations in the volt

Amperes Circuital Law states that the line integral of the magnetic field H around a closed path equals the total current enclosed. ∫ H dl ∑ I App
A small signal amplifier circuit is given in figure Q 4. The values of RD and RS must be set such that the gain of the system is 8. It is also known that Vgs = ¼ Vp. a). Per
This question is about linear filtering concepts using the built in filtering functions (it is not about edge detection methods). Load the MRI image of Q4 above and perform the
