Data processing device, data processing method, and data processing program for evaluation an object based on a persistence diagram from time-series image data

A data processing method, comprising:

• acquiring first data including time-series image data, wherein the first data corresponds to a temporal change of an arc of a circuit interrupter;
• deriving first feature information based on a multidimensional array of n dimensions based on the first data;
• and
• controlling the circuit interrupter by supplying a control signal to the circuit interrupter based on the first feature information, wherein
• n is an integer not less than 3,
• a first axis of the multidimensional array is related to time,
• a second axis of the multidimensional array is related to a first coordinate value of a first spatial axis in space,
• a third axis of the multidimensional array is related to a second coordinate value of a second spatial axis in the space, the second spatial axis crosses the first spatial axis,
• a fourth axis of the multidimensional array is related to a chromaticity coordinate value,
• the first feature information includes a plurality of persistent feature values in a persistence diagram,
• a time of one of the plurality of persistent feature values is different from a time of another one of the plurality of persistent feature values, and
• the persistence diagram corresponds to a dispersion state of at least a portion of the first data, and is derived based on values of the multidimensional array.

A non-transitory computer-readable medium storing instructions that, when executed by one or more processors of a device, cause the device to:

• acquire first data including time-series image data, wherein the first data corresponds to a temporal change of an arc of a circuit interrupter;
• derive first feature information based on a multidimensional array of n dimensions based on the first data;
• and
• control the circuit interrupter by supplying a control signal to the circuit interrupter based on the first feature information, wherein
• n is an integer not less than 3,
• a first axis of the multidimensional array is related to time,
• a second axis of the multidimensional array is related to a first coordinate value of a first spatial axis in space,
• a third axis of the multidimensional array is related to a second coordinate value of a second spatial axis in the space, the second spatial axis crosses the first spatial axis,
• a fourth axis of the multidimensional array is related to a chromaticity coordinate value,
• the first feature information includes a plurality of persistent feature values in a persistence diagram,
• a time of one of the plurality of persistent feature values is different from a time of another one of the plurality of persistent feature values, and
• the persistence diagram corresponds to a dispersion state of at least a portion of the first data, and is derived based on values of the multidimensional array.
