The method includes receiving a plurality of pieces of layer data and classifying the received plurality of pieces of layer data into at least one of two-dimensional (2D) layer data, three-dimensional (3D) layer data, and direct mixed layer data, processing the 2D layer data, mixing the 3D layer data, and mixing the direct mixed layer data, the processed 2D layer data, the processed 3D layer data to generate a display interface.

Methods, systems, computer-readable media, and apparatuses for image processing and utilization are presented. In some embodiments, an image containing at a face of a user may be obtained using a mobile device. An orientation of the face of the user within the image may be determined using the mobile device. The orientation of the face of the user may be determined using multiple stages: (a) a rotation stage for controlling a rotation applied to a portion of the image, to generate a portion of rotated image, and (b) an orientation stage for controlling an orientation applied to orientation-specific feature detection performed on the portion of rotated image. The determined orientation of the face of the user may be utilized as a control input to modify a display rotation of the mobile device.

Systems, methods, and media for adjusting one or more images displayed to a viewer are provided. In some implementations, the system comprises: at least one processing circuit configured to: detect an orientation of a viewer based on at least two points associated with the viewer; determine, based on the orientation, a rotational position of a first image to be displayed on a display; and generate a display image for display on the display, wherein the display image includes at least a portion of the first image rotated based on the rotational position.

Systems, methods, and computer-readable media acquire an image captured with a mobile device. Motion sensor data of the mobile device at or near a time when the image was captured is acquired. An angle of rotation is computed based on the motion sensor data, and the image is transformed based on the angle of rotation. In another aspect, a user interface enables user control over image transformation. The user interface enables user control over rotating an image on a display at two or more granularities. A point of rotation may be user-defined. Rotated images may be scaled to fit within a viewing frame for displaying the transformed image.
