ImageDIG
$49.95 - SciCepts Engineering

ImageDIG consists of three integrated modules which allow the user to convert 2D flat images into 3D (x,y,z) data or if a graph, convert the graph in image form into 2 dimensional numerical data. The third module is a full analysis plotting utility where the user can import either the 2D or 3D data saved above or import any number of columns of data from a file. The data can then be analyzed using several statistical functions and plotted.
