In Bicubic Interpolation values of coefficient ai and bj for 2x come [0.3125 0.9375 -0.3125 0.0625] and [0 1 0 0]. So if pixel matrix P11 to P44 be [235 200 30 200; 235 230 23 200; 20 20 25 20; 235 225 10 235] then output value exceeds the limit of gray values (0-255).

I am not clear about your question

Hey, I was implementing one of your program, bicubic interpolation, but at the time of running the same I am getting neither any error nor the result.How can I get the zoomed image from this..Please help me out. Thank you

it should return a matrix
zoomed_image = function(image, scale);

Hi Please tell me the computational resource requirement for real time implementation of Bi-cubic interpolation over HD video(1920*1080). I want to do this using FPGA. please suggest.

It depends on the way you implement, for example you can do it using or without a buffer data buffer.

Hi, I have developed a system using signal processing technique in matlab. this system will give one string value as a output. now i want to get this output in raspberry pi. How can i do this? many websites say inorder to get in raspberry pi i need create simulink model. how can i solve this?

or else you can use a UART interface to connect raspberry pi and the computer, given that the data rate is not high.

Hi Thilina, I want to input a UTC +GPS time stamp to my Simulink model which performs frequency analysis of voltage signals. Wonder whether there is a direct method for this.

you can use Simulink "From Workspace block" I guess

can you tell me all the things that we can do using matlab?

anything you want.., you name it, they got the toolbox, except you know which ;)

Dear thilina. I hope u will see this. Im currently trying to finish my final yr project proposal and I've ran in to a problem. I am very very interested in learning more about fpga and vhdl.my project supervisor advised me on implementing a ddr3 controller.--please checck the nxt qes.-chanuka

Hi, I do not have much experience with Basys2, I think you can, It will be bit hard, but yes you can, sorry for late reply :)

Hai I am Samantha from university of Jaffna we are now studying bioinformatics for that course we need to know the language PERL do you know about that or do you have any tutorials about PERL

Hi, I don't have any experience in working with PERL. But it seems this is a good tutorial to start with.

What is the function of a transducer? And how it can be compared with sensors?

Vibhatha
Sensor detects a specified form of energy and reports it, where as the Transducer converts one type of an energy into another type.
Ex: Sensor: LDR - Light --> resistance change
Solar Panel: Light --> Electricity

i want to make a save function wch save image effect on the gui insted of save as i imlemented it nd it works correctly but the problem is when i applied 2 effect on image nd press save button they r saved but when 1 apply another effect and press reset button then i got the original image bck i wan

can you send me your code? thilinamees@gmail.com
I will go through it on tomorrow (now 9.35PM in Sri Lanka)

on reset function??

yes, in your program perform your image effects on a copy of the original image. and in the reset, set action as re-assigning the original image into edited image and display

can u tell me how to create a save function in matlab not save as one i pressed the save button i cnt be reset??? plzz help me

I am not clear about your question. but you can use imwrite for saving an image in MATLAB.

I'm a sri lankan student in australia. Can you send me the matlab code for this wihtout using sort option in matlab. Program get 15 numbers from the user and store in a array. then sort it using a function. seek for a quick reply, thanks in advance

Hi, these are the MATLAB/Java/C++ codes I have written for some sorting algorithms, hope this might help you.
