Image identification method, terminal and non-volatile storage medium

An apparatus, comprising:

• interface circuitry configured to receive an image for barcode detection;
• and
• processing circuitry configured to:
• obtain first feature values of a first image feature for pixels in the image for barcode detection;
• calculate measures that are indicative of changes of the first feature values in multiple directions within the image;
• determine a target area in the image for the barcode detection according to the measures;
• divide the target area into a plurality of sub-areas;
• filter the sub-areas to determine a target sub-area for the barcode detection;
• obtain second feature values of a second image feature for the target sub-area, the second image feature being derived from the first image feature;
• and
• identify a barcode type in the target sub-area according to the second image feature.

A non-transitory computer-readable medium storing instructions which when executed by a computer cause the computer to perform:

• obtaining first feature values of a first image feature for pixels in an image for barcode detection;
• calculating measures that are indicative of changes of the first feature values in multiple directions within the image;
• determining a target area in the image for the barcode detection according to the measures;
• dividing the target area into a plurality of sub-areas;
• filtering the sub-areas to determine a target sub-area for the barcode detection;
• obtaining second feature values of a second image feature for the target sub-area, the second image feature being derivative of the first image feature;
• and
• identifying a barcode type in the target sub-area according to the second image feature.
