    Abstract: A method for interactive image caricaturing by an electronic device is described. The method includes detecting at least one feature location of an image. The method further includes generating, based on the at least one feature location, an image mesh that comprises a grid of at least one horizontal line and at least one vertical line. The method additionally includes obtaining a gesture input. The method also includes determining at least one caricature action based on the at least one gesture input. The method further includes generating a caricature image based on the image mesh, the at least one caricature action and the image.

    Abstract: A device (300) for displaying panoramic images includes an image sensor (315), a panoramic display module (345) and a display (325). The display (110, 200) displays an annular panorama view (120, 210). The annular view (120, 210) may be an incomplete annulus for illustrating a missing view angle (126) from an incomplete panoramic image. The display (200) further includes a window (220) and a high resolution display portion (240). The window (220) bounds a portion (230) of the annular view (210). The high resolution display portion (240) displays a high resolution image corresponding to the portion (230) of the annular view (210). The window (220) is movable around the annular view (210). A size of the window (220) or the high resolution display portion (240) is adjustable. A method for generating a panoramic image is also provided.

    Abstract translation: 用于显示全景图像的装置（300）包括图像传感器（315），全景显示模块（345）和显示器（325）。 显示器（110,200）显示环形全景视图（120,210）。 环形视图（120,210）可以是用于示出来自不完全全景图像的缺失视角（126）的不完整环。 显示器（200）还包括窗口（220）和高分辨率显示部分（240）。 窗口（220）限定环形视图（210）的一部分（230）。 高分辨率显示部分（240）显示与环形视图（210）的部分（230）相对应的高分辨率图像。 窗口（220）可围绕环形视图（210）移动。 窗口（220）或高分辨率显示部分（240）的尺寸是可调节的。 还提供了一种用于产生全景图像的方法。

    Abstract: A method performed by an electronic device is described. The method includes receiving an image. The image depicts a face. The method also includes detecting at least one facial landmark of the face in the image. The method further includes receiving a depth image of the face and determining at least one landmark depth by mapping the at least one facial landmark to the depth image. The method also includes determining a plurality of scales of depth image pixels based on the at least one landmark depth and determining a scale smoothness measure for each of the plurality of scales of depth image pixels. The method additionally includes determining facial liveness based on at least two of the scale smoothness measures. Determining the facial liveness may be based on a depth-adaptive smoothness threshold and/or may be based on a natural face size criterion.
