Abstract
A computer implemented method for automatic print analysis, the method comprising: receiving a first image wherein the first image shows one or more of: a latent print, a patent print, an impressed print, and an actual finger, palm, toe and/or foot; and wherein the first image includes characteristic features of at least one of a finger, a palm, a toe and a foot; creating an orientation field by estimating the orientation of one or more features in the first image, wherein the estimating comprises: applying an orientation operator to the first image, the orientation operator being based on a plurality of isotropic filters lying in quadrature.
Claims14
A computer implemented method for automatic print analysis, the method comprising:
- receiving a first image wherein the first image shows one or more of:
- a latent print, a patent print, an impressed print, and an actual finger, palm, toe and/or foot;
- and wherein the first image includes characteristic features of at least one of a finger, a palm, a toe and a foot;
- creating an orientation field by estimating the orientation of one or more features in the first image, wherein the estimating comprises:
- applying an orientation operator to the first image, the orientation operator being based on a plurality of isotropic filters lying in quadrature.
A non-transitory computer readable medium storing instructions that, when executed by a processing device, cause the processing device to perform automatic print analysis, by:
- receiving a first image wherein the first image shows one or more of:
- a latent print, a patent print, an impressed print, and an actual finger, palm, toe and/or foot;
- and wherein the first image includes characteristic features of at least one of a finger, a palm, a toe and a foot;
- creating an orientation field by estimating the orientation of one or more features in the first image, wherein the estimating comprises:
- applying an orientation operator to the first image, the orientation operator being based on a plurality of isotropic filters lying in quadrature.
An electronic computing device comprising:
- a processor;
- and
- a memory;
- wherein the memory stores instructions that when executed by the processor, cause the processing device to perform automatic print analysis, by:
- receiving a first image wherein the first image shows one or more of:
- a latent print, a patent print, an impressed print, and an actual finger, palm, toe and/or foot;
- and wherein the first image includes characteristic features of at least one of a finger, a palm, a toe and a foot;
- creating an orientation field by estimating the orientation of one or more features in the first image, wherein the estimating comprises:
- applying an orientation operator to the first image, the orientation operator being based on a plurality of isotropic filters lying in quadrature.
