Hi! First off, I'm pretty new to the field so bare with me ... I'm trying to implement a method of speech segmentation described in "Landmark detection for distinctive feature-based speech recognition" by Sharlene Lie (JASA Nov. 96) and ran into a couple of questions ... first, I need to compute the spectrogram of the signal I investigate, using a 6-ms hamming window every 1 ms. no prob,...

HI, I would appreciate some help.... I am trying to write a program in MATLAB that will segment moving objects, for example cars, from a series of images (extracting each frame from a video) and that superimposes on each object its bounding box. Has any one got an idea? The images are RGB. and the bounding boxes must be seen on the RGB image not binary or grayscale.

Hi, The best way to learn MATLB is to explore it and check out its features. Image signatures are basically a simple representation of your image or object- rather than looking at a object in 2 dimensions you can extract the important structural information of the image and represent it as a vector. This simplifies your problem. I've already sent a mail about image segmentation- you can

Hello all, A new bee to wavelets, I need to segment a topographic profile (langscape profile sampled at an interval 6 meters extending to 20 kM long) based on the roughness of the profile and also find wavelet power spectrum of it. In that case which wavelet would be the best or can some body pass on to me the necessary matlab code. I would highly appreciate any kind of help. Thanking y...

Dear Friends I am new to DSP. I am trying to implement some speech correction algorithms but I have some problems. Can anyone please provide a matlab m-file code or advice me on how to segment a speech signal which has been read by the wavread function to a vector lets say X. I would be glad for any responses. Best regards G.N

Hello, I need to develop an algorithm that needs to perform a segmentation of a signal according to the local minima(or maxima). The problem is that when I have a noisy time series I can't to this but manually. Can somebody give me an idea on how to deal with this problem? Thank you very much!

hi all i am doing a project on image segmentation where i have to specify the area to be segmented(not exactly but a rough scketch) now how can i get that sketch i draw on the image.i.e. the set of pixels that i mark? (or) is there any way to scribble on a image and get those scribbles as inputs?

Dear friends, I need to segment a set of images. So I am trying to run my segmentation code on the sequence of images one by one. I am facing an interesting problem in MATLAB--that is the code runs faster for first 2 images and slows down for the third one. This problem is consistent. This problem persists if I change the order of the images also. Images are all of same size. I even clea...

Hi all, I am working on particle analysis and I am trying to automate cell count. I came up with an algorithm which first filters the noise , then does segmentation, closes unclosed cells, fills holes and then does cell count. The algorithm works well for some images, however there are problems when this code is applied to images in which the cells are of the same clarity as the backgroun...
