The second scheme is a robust wavelet - based dual watermarking algorithm for copyright protection of the jpeg2000 coded images 二是用于jpeg2000圖象版權保護的小波域魯棒性雙水印算法。
Firstly the paper introduces technology characteristic of ean - 13 and the basic components of the bar code image identification system 本文首先介紹了ean - 13條碼的技術特點以及條碼圖像辨識系統的基本組成。
Embedded image coding is a new coding method and can provide the possibility to progressively reconstruct better and better reproductions of the image as more and more of the coding image bit - stream is received 其中嵌入式編碼是一種新的編碼方式,它可以提供某種程度上的可伸縮性,也就是隨著接收比特的增多,漸進的恢復圖像。
This thesis deals with the application of image segmentation to the automatic identification of a bar code image with a complex background . the bar code image is segmented by the program which is coded by vc + + 6 . 0 , then by image erosion , the background such as characters etc is processed , yielding isolated points which are filtered by a median filter . the relative position of the bar code does not change 本論文將圖像分割應用在有復雜背景的條碼圖像自動識別上,運用vc + + 6 . 0編寫的程序,處理分割的條碼圖像,然后用圖像腐蝕的方法,處理圖像上的文字等背景使其變成一些孤立點,再通過中值濾波去除圖像上的噪聲點,此時圖像中條碼的相對位置不變。
