Deblurring of motion blurred images

I'm looking at an interesting problem of deblurring motion blurred images. Rather than going for guesses of psf, I'm interested in finding out the actual blur parameters (angle and length). I was successful in finding angle of blur to a certain extent, and need a good technique for finding blur length. If any one has a good idea or code ...

(If you don't know what feathering is, check this out - I'm not using dirty language) I know professional design applications like Photoshop can do this, but I would for users to upload images to my site and then display them in a feathered fashion. (Now there's a sentence you don't hear...

How to calculate the rate of change of pixels in matlab

Hi,there are 2 formulae which i am finding it difficult to represent in Matlab. Let there be two RGB images A and B of same size with m,n representing rows and column and the third dimension d=3. The formula1 basically calculates the rate of change of pixels if A be the original image and B be the distorted version. Formula2 calculates t...

Is there a way of programatically detecting whether a photograph is in focus?

If I were building a web service that used a number of photos to illustrate a service, it would be useful to actually detect whether photos are in focus or not. Is there any way of doing this programatically? (Even better, is there an open source implementation of such a routine?) ...

Hey all,     I'm wanting to have a web interface for batch-uploading and resizing images to my server. I've seen quite a few solutions for resizing images client-side, most of them flash based. I really don't care what technology a client-side image resizer uses as long as it: Is reasonably fast Resizes images with some sort of interpo...

The image's dimension is different from when it's loading and after it loads.

I have a page that loads a lot of fairly large images (about 200 of 100Kb images [about 600 x 400 px]). What I'm trying to do is manipulate the photo if it's in portrait, as opposed to landscape. The problem I'm experiencing is that when i use javascript to grab a portrait photo's properties when it's loading, the height is significa...

image information along a polar coordinate system

Hi, I have a set of png images that I would like to process with Python and associated tools. Each image represents a physical object with known dimensions. In each image there is a specific feature of the object at a certain pixel/physical location. The location is different for each image. I would like to impose a polar coordinate s...

Python 2D image generation

Dear experts, What are some of the better libraries for image generation in Python? If I were to implement a GOTCHA (for example's sake), thereby having to manipulate an image on the pixel level, what would my options be? Ideally I would like to save resulting image as a low-resolution jpeg, but this is mere wishing, I'll settle for any...

What image format is easy to turn into on or off pixels?

I have a hobby project that includes me driving a LCD by my serial port. I'd like to display an image with 128x128 pixels, but I'm not sure what image format to use. I'm limited to either "off" or "on" as a state of each pixel. What image format do you recommend? In case it matters, I'm planning on using one of the .NET frameworks wit...

Interpolating 360 degree Images out of only 8 images that are 45 degrees apart

Hi, Sony has demonstrated a very nice technology in Siggraph 2010 where an object can be displayed on a "round LCD" so it could be visible from all directions in 3D without the use of special glasses. This is very nice but in the demonstration movie I saw something that caught my eye. In order to display a 360 degree image they have t...

Although a .Net wrapper (ImageMagick.Net in codeplex) is available but it is still in alpha and does not have implementation for all the command line options e.g Distort, Montage. Therefore I am using System.Diagnostics.Process class to invoke the ImageMagick command line. What are the P...

how to add transparent pixels above and below a 32 bit bitmap images

I need to add at runtime to an inmemory image 15 lines of transparent pixels on top and 20 on the bottom. The images are loaded in a TcxImagelist (from DevExpress Express Library), they can be therefore retrieved as 32bit bitmaps. If the image is 400x75 after the manipulation should be 400x(75+15+20) = 400x110 How to perform this task...
