Abstract
Methods, apparatus, systems and articles of manufacture to detect changes in a physical environment are disclosed. An example apparatus includes a descriptor generator to generate a first descriptor, the descriptor generator including: a chirp producer to emit a chirp into the environment, a chirp recorder to record a response to the chirp from the environment, and a chirp response encoder to generate an encoding of the response to the chirp; a descriptor similarity generator to generate a similarity value, the similarity value to compare the first descriptor to a second descriptor; and a physical change indicator to, in response to the similarity value exceeding a similarity threshold, indicate that a physical change has occurred in the environment.
Claims26
An apparatus to detect a physical change in an environment, the apparatus comprising:
- a descriptor generator to generate a first descriptor, the descriptor generator including:
- a chirp producer to emit a chirp into the environment;
- a chirp recorder to record a response to the chirp from the environment;
- and
- a chirp response encoder to generate an encoding of the response to the chirp;
- a descriptor similarity generator to generate a similarity value, the similarity value to compare the first descriptor to a second descriptor;
- and
- a physical change indicator to, in response to the similarity value exceeding a similarity threshold, indicate that a physical change has occurred in the environment.
A method of detecting a physical change in an environment, the method comprising:
- generating, by executing an instruction with a processor, a first descriptor, the generating including:
- emit a chirp into the environment;
- recording a response to the chirp from the environment;
- and
- generating an encoding of the response to the chirp;
- generating, by executing an instruction with the processor, a similarity value, the similarity value to compare the first descriptor to a second descriptor;
- and
- in response to the similarity value exceeding a similarity threshold, indicating, by executing an instruction with the processor, that a physical change has occurred in the environment.
At least one non-transitory computer readable medium comprising instructions that, when executed, cause at least one processor to at least:
- generate a first descriptor;
- cause a chirp to be emitted into an environment;
- record a response to the chirp from the environment;
- generate an encoding of the response to the chirp;
- generate a similarity value, the similarity value to compare the first descriptor to a second descriptor;
- and
- in response to the similarity value exceeding a similarity threshold, indicate that a physical change has occurred in the environment.
An apparatus to detect a physical change in an environment, the apparatus comprising:
- means for generating to generate a first descriptor, the means for generating including:
- means for causing to cause a chirp to be emitted into the environment;
- means for recording to record a response to the chirp from the environment;
- and
- means for encoding to generate an encoding of the response to the chirp;
- means for comparing to generate a similarity value, the similarity value to compare the first descriptor to a second descriptor;
- and
- means for indicating to indicate that a physical change has occurred in the environment.
