Local Coordinates

A python wrapper for Local Delivery Agents (for example, maildrop), which allows an unlimited number of extensions on a mail account with dot-qmail-like functionality.

This is a demo program of the paper L. Ma, J. Tian, and W. Yu, "Visual saliency detection in image using ant colony optimisation and local phase coherence," Electronics Letters, Vol. 46, Jul. 2010, pp. 1066-1068.

This is a very simple function to find the local maximum in any dimensional array. As simple as it is it still gives nice results.I use the imdilate() function as a maximum operation and then compare the data to the result.The function receives three parameters:the data, a vector defining the...

This function NLMF performs Non-Local Means noise filtering of 1D signal, 2D grey/color or 3D image data. The function is partly c-coded for cpu efficient filtering. Suitable for almost every image data type such as MRI, CT and normal photos.Warning !, Image filtering removes noise, but important...

The problem of fitting a straight line to data with uncertainties in both coordinates is solved using a weighted total least-squares algorithm. The parameters are transformed from the usual slope/y-axis intersection pair to slope angle and distance to the origin. The advantages of this are that...
