A system to improve the stability of inference for the state of a system parameter from a sequence of images of a measuring device with a digital display, the system comprising:
- an image sensor configured to capture the sequence of images of the measuring device with the digital display;
- at least one processor configured to process the sequence of images from the image sensor;
- and at least one memory having stored thereon instructions that, when executed, cause the system to perform:
- extracting digits from the images;
- populating mathematical bins with the digits extracted from the images;
- selecting at least one value that is most frequent based on population of the bins;
- and
- outputting the selected at least one value as representative of one or more digits included in the captured sequence of images.
A method which improves the stability of inference for the state of a system parameter from a sequence of images of a measuring device with a digital display, the method comprising:
- capturing the sequence of images of the measuring device with the digital display using an image sensor;
- extracting digits from the images using at least one processor configured to process the sequence of images from the image sensor;
- populating mathematical bins with the digits extracted from the images using the at least one processor;
- selecting at least one value that is most frequent based on population of the bins using the at least one processor;
- and
- outputting the selected at least one value as representative of one or more digits included in the captured sequence of images such that the stability of inference for the state of the system parameter is improved.
A non-transitory computer readable medium having instructions stored thereon that, when executed by a processer, cause an apparatus to perform a method which improves the stability of inference for the state of a system parameter from a sequence of images of a measuring device with a digital display, the method comprising:
- receiving, from an image sensor, the sequence of the measuring device with the digital display;
- extracting digits from the images;
- populating mathematical bins with the digits extracted from the images;
- selecting at least one value that is most frequent based on population of the bins;
- and
- outputting the selected at least one value as representative of one or more digits included in the sequence of images such that the stability of inference for the state of the system parameter is improved.
