Photo Image Pattern Analysis

Hi Joe, I have a master in computer graphics, good mathematical skills, and the last year, I've been working on barcode readers (projects from ziji in my project history). In both cases, the two first steps are the same: edge detection and edge tracking. But the right approach will depend of the kind of images. There are many questions that can lead to one or other approach: all roads have the same color (then we can use segmentation instead of edge detection), are wide enough (has to do with image resolution), have colored edges, background is monochromatic, images are noisy, burred...well, a large list. The result of these two steps is a set of polylines that join in nodes, i.e a graph. Not sure if you want to store all this data, or just nodes and distance of roads connecting nodes. Anyway, this part of the program looks simple. Conceptually, the problem is easy but all depends on the quality of the images. Just in case, I placed a budget of $1500, once I know the details of the project, I can adjust it. thanks, david.

Hi, I have a PhD and Post Doctorate in image analysis. I think i can solve your problem by using a combination of feature extraction techniques like hough transforms to find lines and curves and segmentation algorithms like adaptive region growing. I will have to look at the pictures first and if possible, i could train a neural net or a support vector machine to actually locate connected road works pixels. but i can definitely decide after looking at some sample images. please send me some data as i dont see any pdf or image files attached. cheers Dr. Asad

A proposal has not yet been provided

Hello sir, Im reading you project descriptions. but i can't see any PDF file include your Porject. Previously i have completed Some project about Graphic work and like your project. I can give you the screen shots of my previously project. for more information or see any screen shot please give me a message. regards: Omid

Dear Dr. Ross: We are a group of engineers and PhD with extensive experience in image processing. Our previous work include boundary detection using PCA and neural network and threshold detection using computational topology. This is documented and published research in peer reviewed journal which we will be glad to share with you. For this project, we will be able to provide a detailed proposal on getting further detail. My first thought off the top of my head is to: (1) Identify the lines by finding the threshold separating the line from the background (2) Find equation of the representative lines (linear regression at the most basic. We can go deep in complexity if required) (3) From the equation, get the angle between the lines using standard formulas in coordinate geometry. We can code it and also make a custom GUI. Contact us for any clarification o some other work.
