Abstract
Imagery is used to identify architectural elements that have known architectural patterns. Feature sets associated with a surface and architectural elements in a building model image are compared with known architectural standards of materials to determine the surface building materials and architectural details of a textured building model. In addition, specific texture patterns can assist final material selections for a repair/replacement.

A method of classifying building materials in an image comprising:
- retrieving an image of a building object;
- identifying contiguous pixels;
- comparing the contiguous pixels against a known building material feature set;
- calculating, based on at least the comparing, a probability that the contiguous pixels represent one or more of a plurality of known building materials;
- and
- determining one of the plurality of known building materials for the identified contiguous pixels of the retrieved image by selecting a highest probability.
A system for classifying building materials in an image comprising:
- an image database configured to retrieve an image corresponding to a building object;
- and
- a processor communicatively coupled to the image database and configured to:
- retrieve an image of the building object;
- identify contiguous pixels;
- compare the contiguous pixels against a known building material feature set;
- calculate, based on at least the compare, a probability that the contiguous pixels represent one or more of a plurality of known building materials;
- and
- determine one of the plurality of known building materials for the identified contiguous pixels of the retrieved image by selecting a highest probability.
A method of classifying building materials in an image comprising:
- retrieving an image of a building object;
- converting contiguous pixels of the retrieved image to frequency domain;
- measuring frequency responses of one or more sections of the image;
- comparing the measured frequency responses against a library of known material frequency responses;
- calculating, based on at least the comparing, a probability that the contiguous pixels represent one of a plurality of known building materials based on the comparing;
- and
- determining one of the plurality of known building materials for the one or more sections of the retrieved image by selecting a highest probability.
