26. A method of measuring a dimension of a first object pictured within an image, wherein a second object having one or more known dimensions is also pictured in the image in the vicinity of the first object, comprising the following steps:
-
the image is displayed for a user on a graphical-user interface; the user selects the identity of the second object from a menu listing two or more objects; upon the user'"'"'s selection of the second object'"'"'s identity, one or more actual dimensions of the second object are retrieved from a memory file for use in subsequent calculations; a displayed measurement tool, capable of being moved, resized, and/or rotated is provided; the measurement tool is positioned and resized by the user over the image of the second object such that the measurement tool'"'"'s borders or endpoint substantially overlay the borders, or endpoints of an axis, of the second object having a known actual dimension; the image size of the second object is determined by mapping the endpoints or borders of the measurement tool to the image file and measuring the image dimension(s) delineated by the icon; a processor means calculates the ratio of actual size to image size by dividing the previously retrieved actual dimension of the second object by the measured image size of the second object; a second measurement tool is displayed which such measurement tool can be moved, resized, and/or rotated; the second measurement tool is positioned and sized by the user such that its borders or endpoints substantially overlay the borders, or endpoints of an axis desired to be measured, of the first object; and using the previously calculated relationship between object size and image size, the actual size of the delineated dimension of the first object is calculated by a processor means. - View Dependent Claims (27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40)

41. A method of measuring a dimension of an object with a mobile device and calculating a statistical rank for the measurement, comprising
using a camera housed in a mobile device to simultaneously acquire an image of a first object having an unknown dimension and a second object wherein at least one dimension is known; -
analyzing the acquired image to determine the degree of minification of the known dimension of the second object; measuring the image size of the dimension of interest of the first object; using the degree of minification of the known dimension of the second object to calculate the actual dimension of the first object; accessing statistics of the population to which the measurement belongs; and calculating a statistical rank for the measured value based on the statistical attributes of the population to which it belongs. - View Dependent Claims (42, 43, 44)

45. A method of measuring the distance between a camera housed within a mobile device and an object of known size, comprising
acquiring an image of the object with the camera, wherein the degree to which the minification of objects in images acquired by such camera varies in a predictable manner as a function of distance from the camera; -
measuring the image size of the object in the acquired image; dividing the measured image size of the object by the known size of the object to determine the degree of minification of the object in the image; and using the calculated degree of minification of the object and the known mathematical relationship between minification and distance for such camera to calculate the predicted distance of the object from the camera. - View Dependent Claims (46, 47)
