Image Saliency Detection Using Image Signatures
no vote
We introduce a simple image descriptor referred to as the image signature. We show, within the theoretical framework of sparse signal mixing, that this quantity spatially approximates the foreground of an image. We experimentally investigate whether this approximate foreground overlaps with visually conspicuous image locations by developing a saliency algorithm based on the image signature. This saliency algorithm predicts human fixation points best among competitors on the Bruce and Tsotsos [1] benchmark data set and does so in much shorter running time.

graph laplacian of the adjacency graph
no vote
 Calculate the graph laplacian of the adjacency graph of data set DATA.  L = laplacian(DATA, TYPE, PARAM)      DATA - NxK matrix. Data points are rows.   TYPE - string 'nn' or string 'epsballs'  PARAM - integer if TYPE='nn', real number if TYPE='epsballs'  Returns: L, sparse symmetric NxN matrix   Example:  L = laplacian(X,'nn',6)  L contains the Laplacian of the graph obtained from connecting  each point of the data set to its 6 nearest neigbours.

maximum likelihood estimates using Gaussian functi
no vote
GGMLE Parameter estimates for generalized Gaussian distributed data.        [MHAT, AHAT, BHAT] = GGMLE(X, OPTIONS)     Returns the maximum likelihood estimates of the parameters of the      generalized Gaussian distribution given the data in the vector X.  OPTIONS (option) is set by OPTIMSET to be used with FZERON  Example:  L = laplacian(X,'nn',6)  L contains the Laplacian of the graph obtained from connecting  each point of the data set to its 6 nearest neigbours.

DWT based color watermarking
no vote
In this project a new watermarking technique has been given which uses DWT transform to embed color watermark on the images. this file also contains the extraction code of the embedded watermarks. In this project example has been demonstrated that how watermark has been embedde as well as extracted from the image.
