For the precise sub-pixel measurement of curves and boudaries in images Included files by Marc Louis Maurice FRANCOIS marc.francois@univ-nantes.fr
=========================== PROGRAMS ==========================
Programs are in capital letters, routines are in lowercase letters. The list of main programs is:
FUNAMBULE is dedicated to curve or silhouette boundaries precise measurements. It uses the VIC method developed by myself (see publications in Doc/Bibliography folder). It is basically a DIC algorithm in which the image is compared to a virtual, user chosen, mathematical curve. The precision of the measurement is sub-pixel and better than every image softwares it has been compared to. Presently available curves are: — B-Splines of various orders, closed or opened — CAD_IBOX is an example of CAD curve — Circle — Ellipse — Polygon of any number of summits — Beams adresses any problem of type y=f(x): Cantilever beam with concentrated force at end Chainette curve Cubic polynomial equation PureFlexion (beam loaded by two opposite momentums) Segment (straight line)
DIGIMCO is a more classical Integrated Digital Image Correlation software (IDIC). The available full-fields are (in folder Champs) : — Corsol for rigid body motion — Defhom for an homogenous strain field — EbHomHPP for an Euler-Bernoulli field of a beam in flexion
DIGIMCO_Q4 is also an IDIC program in which the field is a Q4 finite element one.
YOUNG_POISSON: using DigImCo, this program extracts Young's modulus and Poisson's ratio from a series of images of a tension or compression test along the vertical image axis.
======================== FOLDERS CONTENT ========================
Champs: contains the displacement fields used by DigImCo Curves: contains the curve equations used by Funambule Docs: includes the bibliography on both VIC and DIC and tutorial Images: is the default folder for the images. It actually contains examples for practise. Routines: includes the subroutines of both Digico, Digimco_Q4 and Funambule Routines_graphiques: includes the graphical subroutines of both Digico, Digimco_Q4 and Funambule Temporaire: is the temporary folder in which current images are stored
