摘要: A method and apparatus for detecting text in real-world images comprises calculating a cascade of classifiers, the cascade comprising a plurality of stages, each stage including one or more weak classifiers, the plurality of stages organized to start out with classifiers that are most useful for ruling out non-text regions, and removing regions classified as non-text regions from the cascade prior to completion of the cascade, to further speed up processing.

摘要: A digital image is processed to hide information, by generally inconspicuous adjustments of pixel values. Desirably, the processing is adapted to the particular image being encoded, so as to better conceal the encoding. The method may include determining a relative ability of a pixel to be adjusted inconspicuously, by reference to values of at least two neighboring pixels.
摘要翻译: 处理数字图像以通过对像素值的一般不显着的调整来隐藏信息。 期望地,处理适应于被编码的特定图像,以便更好地隐藏编码。 该方法可以包括通过参考至少两个相邻像素的值来确定要被不明显地调整的像素的相对能力。

摘要: A method and system for embedding signatures within visual images in both digital representation and print or film. A signature is inseparably embedded within the visible image, the signature persisting through image transforms that include resizing as well as conversion to print or film among the pixels of an original image. The pixel values of the signature points and surrounding pixels are adjusted by an amount detectable by a digital scanner. The adjusted signature points form a digital signature which is stored for future identification of subject images derived from the image. In one embodiment, a signature is embedded within an image by locating relative extrema in the continuous space of pixel values and selecting the signature points from among the extrema. Preferably, the signature is redundantly embedded in the image such that any of the redundant representations can be used to identify the signature. Identification of a subject image includes ensuring that the subject image is normalized with respect to the original image or the signed image. Preferably, the normalized subject image is compared with the stored digital signature.

摘要: A digital image in which hidden information has been encoded, is processed to discern the hidden information. This processing can include identifying geometric distortions of the image (e.g., cropping, scaling, rotation), and compensating for such identified distortions.
摘要翻译: 隐藏信息被编码的数字图像被处理以辨别隐藏的信息。 该处理可以包括识别图像的几何失真(例如,裁剪,缩放,旋转)以及补偿这些所识别的失真。

摘要: The present invention relates to hiding codes in input data. In one embodiment, a method is provided including: obtaining input data associated with image or visual information; selecting portions of the input data to hide a plural-bit code based at least in part on predetermined data; and modifying selected portions of the input data to hide the plural-bit code at least in part on changing one or more values of the input data at or around the selected portions. Other embodiments are described and claimed as well.
