Abstract
A computer alters at least one recognizable metric or text in a digitally encoded photographic image by operating an alteration algorithm in response to user input data while preserving an overall aesthetic quality of the image and obscuring an identity of at least one individual or geographic location appearing in the image. An altered digitally-encoded photographic image prepared by the altering of the at least one recognizable metric or text in the image is stored in a computer memory. User feedback and/or automatic analysis may be performed to define parameter values of the alteration algorithm such that the alteration process achieves preservation of aesthetic qualities while obscuring an identity of interest.
Claims6
A system to impair automated moving image analysis, comprising:
- a processor coupled to a memory, the memory encoded with instructions that when executed by the processor, cause the system to:
- analyze a digitally-encoded moving image comprising one or more persons walking;
- apply a Clothing Display to at least one person to alter an apparent gait of the person using an alteration algorithm that identifies an alteration of gait metrics based on a value of:
- Δ
- =
- ∑
- 1
-
- to
-
- M
- ∂
- i
- _
- to substantially reduce risk of automatic recognition of the apparent gait while preserving an overall aesthetic quality of the apparent gait, wherein ∂l is a measure of metric alteration of each of a number M of the gait metrics;
- and
- store in the memory, an altered digitally-encoded image.
