    • An image processing method, performed by a computer, for generating, from a source image (21), a rotated image of modified size (29) is disclosed. The method comprises obtaining a rotated image by compensating the source image rotation according to an information representative of the rotation of the source image; determining (24) one rectangular image part (25a) in the rotated image according to information representative of the perceptual interest associated with each pixel of the rotated image; obtaining a rotated image (29) of modified size by modifying the size of the rectangular image part (27a) in the rotated image according to a ratio between the width and height of the rectangular image part and according to an information representative of the rotated image. Alternative embodiments for image processing method as well as apparatus implementing the method are further described.
    • 公开了一种由计算机执行的用于从源图像(21)生成经修改尺寸(29)的旋转图像的图像处理方法。 该方法包括通过根据表示源图像的旋转的信息补偿源图像旋转来获得旋转图像; 根据表示与旋转图像的每个像素相关联的感知兴趣的信息,确定(24)旋转图像中的一个矩形图像部分(25a) 通过根据矩形图像部分的宽度和高度之间的比率修改旋转图像中的矩形图像部分(27a)的尺寸并根据表示旋转图像的信息来获得修改尺寸的旋转图像(29) 。 进一步描述图像处理方法的替代实施例以及实现该方法的装置。

    • The invention relates to a method for displaying a sequence of pictures coming in the form of a multilayer stream comprising a base layer representative of the pictures of the sequence at a first resolution and/or first quality and at least one enhancement layer representative of the sequence pictures at a second resolution and/or second quality. The method comprises the following steps: - decode (100) the base layer from a random access point of the base layer and at least up to the decoding of a random access point of the enhancement layer to reconstruct pictures of the base layer, - display (110) the reconstructed pictures of the base layer, - decode (130) the enhancement layer from the random access point of the enhancement layer to reconstruct pictures of the enhancement layer, and - display (150) the reconstructed pictures of the enhancement layer. The method further comprises a processing step (140) of the pictures of the enhancement layer before their display in such a way that the variation of the image content and/or of its quality between the picture of the base layer corresponding to the time of the random access point of the enhancement layer and the pictures of the enhancement layer is gradual.
    • 本发明涉及一种用于显示以多层流形式出现的图像序列的方法,包括以第一分辨率和/或第一质量表示序列的图片的基本层和表示序列的至少一个增强层 图像以第二分辨率和/或第二质量。 该方法包括以下步骤: - 从基本层的随机接入点解码(100)基层,并至少直到对增强层的随机接入点的解码,以重构基层的图像; - 显示 (110)所述基本层的重建图像, - 从所述增强层的随机接入点解码(130)所述增强层,以重构所述增强层的图像,以及 - 显示(150)所述增强层的重建图像。 该方法还包括增强层在其显示之前的图像的处理步骤(140),使得图像内容的图像和/或其质量在基底层的图像之间的变化对应于 增强层的随机接入点和增强层的图像是渐进的。
