摘要： The invention concerns a method for classifying a colour image to determine whether it is an interior or exterior shot, characterised in that it consists in: determining reference colour spectral bands Bi corresponding to different temperature values of an image, enabling to characterise an exterior image or an interior image; selecting a colour image to be analysed, digitising the selected colour image so that it is defined in a specific colour space (for example RGB); determining for at least the reference colour spectral bands, the distribution of the colour spectra of at least part of the colour image; and analysing the digitised image colour spectra so as to determine, on the basis of their distribution in accordance with the reference colour spectral bands, whether the image temperature correspond to an interior or and exterior image.
摘要翻译：本发明涉及一种用于对彩色图像进行分类以确定其是内部还是外部镜头的方法，其特征在于，该方法包括：确定对应于图像的不同温度值的参考色谱带Bi，能够表征外部图像或内部图像; 选择要分析的彩色图像，数字化所选择的彩色图像，以使其在特定的颜色空间（例如RGB）中定义; 针对至少所述参考色谱带确定所述彩色图像的至少一部分的色谱的分布; 以及分析数字化的图像色谱以基于其根据参考色谱带的分布来确定图像温度是对应于内部图像还是外部图像。

摘要： Disclosed is a system for automatically locating text areas in a digital image, comprising a unit (150, 160) that converts an input digital image into a binary image, a unit (170) which locates potential text areas that are applied to the binary image, and a unit (180) which selects actual text areas highlighted by the locating unit (170). The unit (170) locating potential text areas is advantageously provided with means for applying at least one morphological filter to the binary image that results from the conversion of the digital image into a binary image. The selecting unit (180) carries out a method for dividing the intensity of gray levels applied to the image supplied by a processing unit (160) that is included in the unit (150, 160) converting the digital image into a binary image.
摘要翻译：公开了一种用于自动定位数字图像中的文本区域的系统，包括将输入数字图像转换为二进制图像的单元（150,160），定位应用于二进制图像的潜在文本区域的单元（170），以及选择由所述定位单元（170）突出显示的实际文本区域的单元（180）。定位潜在文本区域的单元（170）有利地设置有用于将至少一个形态滤波器应用于由数字图像转换为二进制图像而产生的二进制图像的装置。选择单元（180）执行用于将应用于由将数字图像转换为二进制图像的单元（150,160）中包括的处理单元（160）提供的图像应用的灰度级的强度分割的方法。

摘要： Classification process for a colour image with a view to determining the shot location, i.e. exterior or interior, consisting in particular of the following: determining spectral bands of reference colours Bi corresponding to different image temperature values allowing for the characterisation of an exterior image or an interior image, selecting a colour image to be analysed, digitising the selected colour image so that it can be defined in a given colour area (for example RGB), determining at least for the spectral bands of the reference colours the distribution of colour spectrums of at least part of the digitised colour image, and analysing the colour spectrums of the digitised image in order to determine the temperature of the image corresponding to an interior image or an exterior image depending on their distribution according to the spectral bands of reference colours.
