Explain briefly the operation, draw the functions, formulas and observations.
(i) Write an m-file "imnorm.m" which takes an image finds min and max values and uses them to normalize the image.
What kind of image enhancement operation is performed within that function? Draw an illustration.
Write an m-file for each of the following operations: (ii) compute negative image (neg.m)
(iii) apply power law transform with a superscript 0.2 (powlaw.m)
(iv) perform histogram equalization of an image (hist_eq.m) it should display 5 figures: the input image and its histogram the integral histogram the output image and its histogram the following function will give you a histogram of pixel values between 0 and 255 h=sum(hist(im,[0:255])'); %help hist; help sum; stem(h,'.k');
function imh=hist_eq(im); figure(1); imshow(?); h=? figure(2) stem(?); % compute integral image hint=h; for i=2:256 hint(i)=hint(i-1)+h(i); end hint=255*hint/hint(end); %normalize the integral histogram to have values between 0 and 255 figure(3) stem(?); imh=hint(im);%modify pixel intensities imh=uint8(imh);%normalize to byte values figure(4) imshow(?) h=? figure(5) stem(?);
What histogram equalization does? What should be the shape of the output histogram? Why it isn't?
Kirchoff's Current Law The total current entering a node in a circuit is equal to the total current leaving that node. A Node is a junction between two or more components.
Permanent magnets are made of (A) Soft magnetic materials. (B) Hard magnetic materials. (C) Semi conductors. (D) Super conductors.
With respect to serial communication define the asynchronous communication. Asynchronous implies "no synchronization", and therefore does not require sending and receiving idl
Q. Explain with the help of a circuit diagram,the operation of COLPITTS OSCILLATOR. Oscillator is a circuit used to generate a.c voltage without a.c.input signal.The energy to
Q. J and K are the external inputs to the JKFF shown in Figure. Note that gates 1 and 2 are enabled only when the clock pulse is high. Consider the four cases of operation and expl
Level 1 is means of sending bit streams over a physical path. It uses times lot 16 of a 2 M bit/s PCM system or times slot 24 of a1.5 M bit/s system. Level 2 performs functions
1. Why must a modem be used to transmit binary data through a PSTN? (1) Use sketches and additional text to describe the following modulation methods. (a) Amplitude shift key
List out the five categories of the 8085 instructions. Give examples of the instructions for each group. 1. Data transfer group - MOV, MVI, LXI. 2. Arithmetic group - ADD,
