摘要： The invention related to a method for detection of points of interest in a source digital image, by means of a wavelet transformation associating a sub-sampled image, called a scaled image, with a source image and wavelet coefficients corresponding to at least one detail image, for at least one level of decomposition, a point of interest being a point associated with a region of the image with high frequencies. The method comprises the following steps:—application of said wavelet transformation to said source image, generation of a single tree structure from the wavelet coefficients of each of said detail images and selection of at least one point of interest by analysis of said tree structure.

摘要： The invention relates in particular to a method of scrambling a video signal using an encryption key for controlling access to audiovisual information. The video signal is scrambled by applying a tattooing function to the video signal by using a marking key derived from the encryption key, the tattooing function including a parameter for regulating the amplitude of tattooing so as to enable the visibility of the tattooing in the video signal to be adjusted. The invention also provides a dual unscrambling method, and a system, an encoder, a decoder, a broadcast server, and a data medium for implementing said methods.

摘要： The present invention relates to a method of real-time on-line auction processing implemented by a bid server, comprising the following steps: reception of bid orders relating to at least one good or service put up for sale by auction, each bid order being associated with an amount; selection of a bid order, from among the bid orders received whose amount is equal to the highest amount of all the bid orders received. Furthermore, in this method a timeout is triggered whenever the server receives a bid order of an amount strictly greater than the highest amount of all the bid orders received previously and relating to the said good or service; and during the selection step, a bid order is selected randomly from among those received during the timeout period. The invention applies also to two other types of auction methods in which the price of the good or service put up for sale is fixed by the server.

摘要： The invention relates to a method for recognizing faces in digital images consisting in providing for a knowledge base which contains face images and is hierarchical into several classes each of which comprises different images of the same person. The invention relates to pre-processing said knowledge base in such a way that a minimization of variance in each class and a maximization of variance between different classes are simultaneously obtainable, thereby making it possible to form a vectorial base comprising the discriminant component of said knowledge base. The comparison of a recognizable face with a pre-processed reference face such as the knowledge base and an eventual reconstruction of a recognized face are also disclosed.

摘要： Pixels are classified as text; or “non-text” by responding to accumulated luminous brightness gradients within a predetermined pixel interior. Text and non-text image characteristics rest on estimating text-containing rectangles by determining a narrow width and a height of a peak in an interval of accumulated gradients around each pixel. The text characteristics also are inferred by detecting character corners by quantifying and smoothing gradient angles and by associating directional corner responses with each pixel.
摘要翻译： 像素被分类为文字; 或“非文本”，通过响应在预定像素内部的累积的发光亮度梯度。 文本和非文本图像特征依赖于通过确定围绕每个像素的累积梯度的间隔中的峰值的窄宽度和高度来估计包含文本的矩形。 通过量化和平滑梯度角以及通过将方向角响应与每个像素相关联来检测文字角，推断文本特征。
