![]() Here is the detailed performance test result: SDK It covers typical distortions, such as inhomogeneous illumination, reflections, or blurriness due to camera movement. The dataset contains 1054 valid barcode images in real-life. Performance Test Result on Muenster BarcodeDB The test result on out-of-focus images dataset 2: SDK Dataset 2 contains pictures taken by devices without AF. Dataset 1 contains pictures of barcodes taken from devices with the autofocus (AF) function. ![]() The Artelab Medium Barcode 1D Collection has two sets of images. Performance Test Result on Artelab Medium Barcode 1D Collection If the SDK reads the unannotated barcode, it is not considered as mis-read. Some images contain multiple barcodes while in the annotation, only one barcode is annotated.If a barcode is recognized as UPC-A and the ground truth is in EAN13 format (the EAN13 format has one extra leading zero), it is considered as correct.The annotations are examined and corrected manually to avoid errors. We ran a performance test on the three datasets mentioned above. Reading rate = correct results / all barcodes Performance Test Results For example, if a barcode is mistakenly recognized as two separate ones, this behavior would not lower the reading rate. A precision of 100% means that all the barcodes were recognized successfully, although there might be wrong values mixed in with the results. The reading rate is the number of correct results divided by the number of all barcodes. Precision = correct results / all returned results A precision of 100% means each of the results is correct, although some barcodes might be missed. The precision is the number of correct results divided by the number of all results. In this article, we use precision and reading rate to evaluate the accuracy. Datasetīarcodes are relatively large compared to the image size We have compiled a table of existing publicly available barcode datasets. In this comprehensive analysis, we put compare Dynamsoft’s barcode SDK against another commercial barcode SDK and two popular open source solutions, Zbar and ZXing. We will discuss the datasets in the following section. This article uses the barcode values to measure barcode scanning accuracy. Both approaches can be used to compare different barcode scanning engines. In this step, the barcode scanner tries to unravel the encoded data.Ĭorresponding to the two steps, some datasets mark up the coordinates of the barcode candidates, while others mark up the barcode encoded values. Decode (AKA recognition) - Once the regions of interest are identified, decoding is then initiated.One or more coordinates of quadrilaterals are returned. Detection (AKA localization) - Upon initiating a scan, a barcode engine scans the entire width of an image trying to identify whether there are barcode candidates.How to Evaluate Barcode Scanning Accuracy Multiple Barcodes Reading Benchmark and Comparison What are the Best Data Matrix Reading SDKs?
