Hello, I'm following a course of digital image processing and a mathematical homework is first given. I need a little help for solving this problem: What is the impulse response of the system: 1/ if its transfer function is G(z1,z2) =3D a + b.z1^(-1) + c.z2^(-1) + d.z1^(-1).z2^(-1) + e.z1.z2^(-1) 2/ if its frequency response if G(f,g) =3D a + b.cos(2*Pi*f) + c=2Ecos(2*Pi*g) A...

We're all familiar with typical plot (eg http://en.wikipedia.org/wiki/Image:Bandwidth2.png) used in typical explanations of Q. What's the analytical expression represented by that curve? [Yeah I should be able to derive it from first principles, but can't seem to do anything right today ;[ TIA

Hi I would like to develop a CDF 5/3 (LeGall 5/3) lifting wavelet in an FPGA so that I can do some image processing. Reading through some papers I have found the algorithm to code but I would like to perform the same thing in Matlab so that I can check my results. Can someone who knows about the wavelet toolbox tell me the required commands, so that I can enter a sequence of values and get the ...

Hi, I'm using fft convolutions for image registration: x=fftconvolve(img1,img2) I want to compare the alignment between multiple pairs of images. I assume the magnitude of x contains this information, but is there something I should do to standardise it?

I read in some paper that you can synthesize a sharp image by adding together Gaussian smoothed data. That seems very surprising at first. I tried it in a particular context and it works.

For 1D signal processing if we have an FIR filter then we can write y(k)=W'X(k) where W is a vector of weights and X(k) is composed of past values of input. For the 2D case we may have Y=H.X where H is a mask. What is X? Is it just intensities ie grey scale since time doesn't come into it.It is spacial. Also, does anybody use recursive 2D filters? I assume the stability may be a prob...

hello everyone, about the trimedia board, does anyone knows what the board really is? i mean is it a different type of hardware platform for image/video processing. IMHO, there are dsp, fpga and ASIC. so where do we put the trimedia?

Hello, I am trying to an image camera for doing some DSP work. I want to have it to connect to my C6711DSK board. I have heard that there are some that allows one to read a full line of pixels upon a clock trigger, which could be easily generated with the DSK. But so far I have only been able to find video cameras with NTSC signal output, which requires a frame grabber. For still images,...

hi all, I have for a student project to develop a software compressing images by the Karhunen-Loeve Transform (KLT) method. I've read 3 days and did not found anything useful in Google. :(( if anybody of you can send me something similar that he has developed or give me link with a good example i will be really grateful. thanks,

Hi: I would like your advice please. I've been working as a non-DSP programmer for a few years. I am looking to gain expertise in DSP and TI320C6x to find a job in the area. I bought 'Embedded Image Processing on the TMS320C6000 DSP (Qureshi)' and just downloaded CCStudio intending to do all the projects. Will this be enough to get me noticed by employers? What else can I do? Do yo...

Hi all, I am currently doing a fftw_2d_r2c and i want to know if I must normalize my datas to get a relevant representation of the real part and the imaginary part in the frequency domain. Assuming that i have an image of size nx*ny, I have supposed that I should divide by sqrt(nx*ny), is this right? Greetings, Greg
