Abstract
A method of analyzing and assessing an image comprises the steps of: (a) obtaining said image in a digital form; (b) processing said image; and (c) establishing at least one edge line within said image. The step of processing said image further includes: (a) building a 3D graph of intensity distribution within said image; (b) calculating identifying vector angle values (IVAVs); said angles adjoin to points of said 3D intensity distribution graph which correspond to individual pixels of said image; said angles lie in a plane defined by an intensity axis of said image; (c) setting a range of lower and upper thresh-hold level values (THLV1 and THLV2) between which edge points are indicatable; and (d) indicating edge points according to said THLV1 and THLV2.

A method of analyzing and assessing an image, said method comprising steps of:
- a. obtaining said image in a electronic or digital form;
- b. processing said image;
- and
- c. establishing at least one edge line within said image;
- wherein said step of processing said image comprises:
- a. building a 3D graph of intensity distribution within said image;
- b. calculating identifying vector angle values (IVAVs);
- each angle adjoins to a point of said 3D intensity distribution graph which corresponds to an individual pixel of said image;
- said angle lies in a plane defined by an intensity axis of said image and are formed by lines being tangent to said 3D graph of intensity distribution located at nearest neighbor pixels to said individual pixel;
- c. setting a range of lower and upper thresh-hold level values (THLV1 and THLV2) between which edge points are indicatable;
- and
- d. indicating edge points according to said THLV1 and THLV2.
A device for analyzing and assessing an image;
- said device comprising:
- a. a unit configured for electronic or digital input of said image;
- b. a processor configured for analyzing and assessing said image;
- c. an interface unit configured for controlling said device and displaying processed images and contiguous data;
- wherein said processor is further configured for:
- a. building a 3D graph of intensity distribution within said image;
- b. calculating identifying vector angle values (IVAVs);
- each angle adjoins to a point of said 3D intensity distribution graph which corresponds to an individual pixel of said image;
- said angle lies in a plane defined by an intensity axis of said image and are formed by lines being tangent to said 3D graph of intensity distribution located at nearest neighbor pixels to said individual pixel;
- c. setting a range of lower and upper thresh-hold level values (THLV1 and THLV2) between which edge points are indicatable;
- and
- d. tracing said edge points according to said THLV1 and THLV2.
A non-transitory computer-readable medium having thereon software instructions configured to cause a processor to perform operations comprising:
- a. obtaining said image in an electronic or digital form;
- b. establishing at least one edge line within said image;
- wherein said operation of processing said image comprises:
- a. building a 3D graph of intensity distribution within said image;
- b. calculating identifying vector angle values (IVAVs);
- each angle adjoins to a point of said 3D intensity distribution graph which corresponds to an individual pixel of said image;
- said angle lies in a plane defined by an intensity axis of said image and are formed by lines being tangent to said 3D graph of intensity distribution located at nearest neighbor pixels to said individual pixel;
- c. setting a range of lower and upper thresh-hold level values (THLV1 and THLV2) between which edge points are indicatable;
- and
- d. tracing said edge points according to said THLV1 and THLV2.
