This submission consists of a presentation file and color calibration demo used during the the webinar titled "Color Image Processing with MATLABdlTÂ« that was held on June 28th, 2007.
Calculating Distances between points on the image
An implementation of the image normalization (and inverse normalization) part of P. Dong et al.'s paper: "Digital Watermarking Robust to Geometric Distortions," IEEE Trans. Image Processing, Vol. 14, No. 12, pp. 2140-2150, 2005.
The function checks that the image matches the TIFF specification, and checks that the image is neither a black-out or a white-out or that there is no one frequency dominating.
To display grids on image
This demo show how to use JP4 image.

This model presents how one may be able to detect whether an image is in or out of focus using the FFT. StateflowdlTÂ« is used to manage state behavior; the model also makes use of Embedded MATLAB and integration of legacy C code. When running...
Using the Image Acquisition and Image Processing Toolboxes, IMAQMOTION offers a MATLAB based motion detection GUI.
Using a video input object, live data is acquired and analyzed to calculate any motion between two adjacent image...
Convert Image To TExt Characters
And We Can Send File With Rs232
COMPUTES STATISTICAL MEASURES OF TEXTURE IN AN IMAGE
LIKE CONTRAST,CORRELATION, ENERGY & HOMOGENEITY
Wavelet based square image enlargemant (zooming in).
Zooming is performed by employing the idwt2() MATLAB function, with a wavelet
family determined by 'wname'.
The size and quality of the final zoomed image 'output_image' depends on
Function which can convert image formats supported by Matlab to high-quality .eps file. Can be useful for use with latex.
The histogram of the image gives the frequency of occurrence of the gray level. it gives the no. of times a particular gray level occurs in the image. In the case of a colour image,the histogram is expected to give the number of a particular...
this code does gray scale image compression
to use this codes u have to first convert RGB image to grayscale and also its colormap.....
Image segmentation using Quatree
The program loads an image and then perform segmentation using Quadtree Segmentation
first read any two image in command window then press ctrl+enter to execute each cell .highlight duller value nd increase or decrease the value from cell box to increase or decrease the image
This program makes an easy understanding of Image Processing on MATLAB.
The folder contain test image on which letter extraction is applied. You can run this code on different images.
This m-script slices 3D image file in MovingMask.raw in 2D images.
Read and preview of Leica's image format file.
-- Usage --
1. In matlab prompt,
GUI window to pick a file will open.
