Abstract
Systems and methods for detecting image anomalies include extracting one or more detected images from a submission file received from at least one computing device and generating an image identification (ID) for each of the one or more images. One or more image quality indices are determined for the submission file based on at least one of predetermined image features, an image type of the one or more images, and submission file attributes, and one or more image anomalies associated with the one or more images of the submission file are detected based on at least one of the image ID and the one or more image quality indices.
Claims18
A device comprising:
- processing circuitry configured to:
- extract one or more images from a submission file obtained from at least one computing device,
- generate, for each of the one or more images, an image identification (ID) value as a combination of pixel brightness values of the respective image,
- determine one or more image quality indices for the submission file based on at least one of predetermined image features, an image type of the one or more images, and submission file attributes, and
- detect one or more image anomalies associated with the one or more images, wherein the one or more image anomalies include at least one of image duplication anomalies detected based on the image ID values of two or more of the images, image quality anomalies detected based on the image quality indices, and image modification anomalies detected based on at least one of the image ID values or the image quality indices.
A method comprising:
- extracting, by processing circuitry of one or more computing systems, one or more images from a submission file obtained from at least one computing device;
- generating, by the processing circuitry, an image identification (ID) value for each of the one or more images as a combination of pixel brightness values of the respective image;
- determining, by the processing circuitry, one or more image quality indices for the submission file based on at least one of predetermined image features, an image type of the one or more images, and submission file attributes;
- and
- detecting, by the processing circuitry, one or more image anomalies associated with the one or more images, wherein the one or more image anomalies include at least one of image duplicate anomalies detected based on the image ID values of two or more of the images, image quality anomalies detected based on the image quality indices, and image modification anomalies detected based on at least one of the image ID values or the image quality indices.
A non-transitory computer readable medium having instructions stored thereon, wherein the instructions, when executed by processing circuitry, cause the processing circuitry to perform a method comprising:
- extracting one or more images from a submission file obtained from at least one computing device;
- generating, for each of the one or more images, an image identification (ID) value as a combination of pixel brightness values of the respective image;
- determining one or more image quality indices for the submission file based on at least one of predetermined image features, an image type of the one or more images, and submission file attributes;
- and
- detecting one or more image anomalies associated with the one or more images, wherein the one or more image anomalies include at least one of image duplicate anomalies detected based on the image ID values of two or more of the images, image quality anomalies detected based on the image quality indices, and image modification anomalies detected based on at least one of the image ID values or the image quality indices.
