Abstract

The watermark detection method under Android system combines the technology of computer vision, image processing and pattern matching, aiming to provide an effective and automatic watermark detection solution. Through image conversion of input files and pre-processing operations such as filtering, contrast enhancement and brightness adjustment, the watermark features of files in different formats are enhanced. Feature extraction algorithm is adopted to extract features such as the number and hierarchical relationship of image contouring from pre-processed images, and image features are further processed by fitting algorithm. Finally, it is compared and matched with the predefined watermark pattern library. By combining the image recognition algorithm with Android components, the system realizes the watermark detection function in Android applications.
