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:
- at least one memory;
- computer readable instructions;
- and
- at least one processor to execute the computer readable instructions to at least:
- determine a first location for a first descriptor, the first descriptor including an encoded response of the environment to an audio signal;
- generate the first descriptor for the first location, the first descriptor generated by:
- emitting the audio signal into the environment;
- recording a response to the audio signal from the environment;
- and
- generating an encoding of the response to the audio signal;
- generate a similarity value, the similarity value to compare the first descriptor to a second descriptor, the first descriptor and the second descriptor including a local weather of the environment in which the response to the audio signal is recorded;
- and
- 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:
- determining, by executing an instruction with a processor, a first location for a first descriptor, the first descriptor including an encoded response of the environment to an audio signal;
- generating, by executing an instruction with the processor, the first descriptor, the generating including:
- emitting the audio signal into the environment;
- recording a response to the audio signal from the environment;
- and
- generating an encoding of the response to the audio signal;
- generating, by executing an instruction with the processor, a similarity value, the similarity value to compare the first descriptor to a second descriptor, the first descriptor and the second descriptor including a local weather of the environment in which the response to the audio signal is recorded;
- 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:
- determine a first location for a first descriptor, the first descriptor including an encoded response of an environment to an audio signal;
- generate the first descriptor;
- cause the audio signal to be emitted into the environment;
- record a response to the audio signal from the environment;
- generate an encoding of the response to the audio signal;
- generate a similarity value, the similarity value to compare the first descriptor to a second descriptor, the first descriptor and the second descriptor including a local weather of the environment in which the response to the audio signal is recorded;
- 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 determining a first location for a first descriptor, the first descriptor including an encoded response of the environment to an audio signal;
- means for generating to generate the first descriptor, the means for generating including:
- means for causing to cause the audio signal to be emitted into the environment;
- means for recording to record a response to the audio signal from the environment;
- and
- means for encoding to generate an encoding of the response to the audio signal;
- means for comparing to generate a similarity value, the similarity value to compare the first descriptor to a second descriptor, the first descriptor and the second descriptor including a local weather of the environment in which the response to the audio signal is recorded;
- and
- means for indicating to indicate that a physical change has occurred in the environment.
