	NLREG | License: Demo |
	NLREG performs nonlinear regression and curve fitting. NLREG fits a mathematical function whose form you specify to a set of data values. Virtually any type of function can be fitted. NLREG includes a programming language similar to C that you use for describing the function to be fitted. Two dimensional line and three dimensional surface plots can be generated. The programming language includes a large selection of built-in library functions (sin, cos, log, exp, etc.) that makes it easy to describe complicated models. Publisher: Phillip H.

	CurvFit | License: Freeware |
	CurvFit (tm) is a curve fitting program for Windows. Lorentzian, Sine, Exponential and Power series are available models to match your data. A Lorentzian series is highly recommended for real data especially for multiple peaked and/or valleys data. CurvFit is an example of Calculus programming... ie. minutes to solve, days or years to understand solution and what it implies (e.g. wrong model, sampling rate error, etc.). Helps learn 1) whether math model is good for given data; 2) convergence implies a reasonable solution; 3) how to select new starting initial parameter values.

	Curve Pilot for Mac | License: Demo |
	Curve Pilot designed for teaching the basics of color corrections of images created by a digital camera or scanner. The traditional image editors use the curve method for color correction. The drawback of this method is that you don't always understand in which direction you should move certain curve. Curve Pilot offers you a revolutionary new method: simply indicate which color you want to get as a result of color correction and Curve Pilot will automatically calculate the values for curves that allow you to achieve the goal.

	VectorEye | License: Shareware |
	VectorEye is a great raster to vector converter that exports to SVG (Scalable Vector Graphics), Ps, Eps, Flash macromedia and xaml windows vista. It recognizes all major raster formats (BMP, JPEG, PNG, TIFF). Tint area and line converter. Raster images made from pixels acquired from scanner or CCD camera can be translated into scalable geometric shapes. Vector based images are the best way to display high quality graphics with the minimum amount of information. Extracting this information from raster images is a great challenge, and algorithms will probably never replace our artistic sensitivity. Publisher: Siame | Date: 01-09-2007 | Size: 6574 KB
