This paper presents a new quality parameter for edge generation of two-dimensional images via spline interpolation.
The motivation of the study is to define a parameter which allows establishing a stop criterion for inserting image data and obtaining a representation via spline that is sufficiently faithful. The parameter is deduced by an iterative calculation process between areas limited by cubic and linear splines after insertion of points. Then, after convergence, the parameter qualifies the fidelity of the computational representation of the image. The numerical code is developed from the octave software, and some images were generated validating the new parameter.
