DeconvolutionMode
DeconvolutionMode
Deconvolution (image restorations) mode which defines level of image degradation. Originally deconvolution is a function which can restore image degraded (convoluted) by any natural function like blur, during obtaining image by camera. Because we cannot detect image function which corrupt the image, we have to check most well know functions like sharp or mathematical morphology. This sample shows how to use Deconvolution mode let reader = new BarCodeReader(“test.png”, null, [DecodeType.CODE_39_FULL_ASCII, DecodeType.CODE_128]); reader.getQualitySettings().setDeconvolution(DeconvolutionMode.SLOW); let results = reader.readBarCodes(); for(let i = 0; i < results.length; i++) { let result = results[i]; console.log(“BarCode CodeText: " + result.getCodeText()); }
