ADAPTIVE DEPTH-GUIDED NON-PHOTOREALISTIC RENDERING METHOD, CORRESPONDING COMPUTER PROGRAM PRODUCT, COMPUTER-READABLE CARRIER MEDIUM AND DEVICE
A method for rendering a non-photorealistic (NPR) content from a set (SI) of at least one image of a same scene is provided. The set of images (SI) is associated with a depth image comprising a set of regions. Each region corresponds to a region of a given depth. The method for rendering a non-photorealistic content includes generation of a segmented image having at least one segmented region generated with a given segmentation scale. The at least one segmented region corresponds to at least one region of the set of regions. A binary edge image is generated in which at least one binary edge region is generated with a given edge extraction scale, the at least one binary edge region corresponding to at least one region of the set of regions. The non-photorealistic content is rendered by combining the segmented image and the binary edge image.
Face pose rectification method and apparatus
A pose rectification method for rectifying a pose in data representing face images, comprising the steps of: A—acquiring a least one test frame including 2D near infrared image data, 2D visible light image data, and a depth map; C—estimating the pose of a face in said test frame by aligning said depth map with a 3D model of a head of known orientation; D—mapping at least one of said 2D image on the depth map, so as to generate textured image data; E—projecting the textured image data in 2D so as to generate data representing a pose-rectified 2D projected image.

The multi-aperture imaging device is provided with a first plurality of optical channels for projecting overlapping first partial fields of view of a total field of view on first image sensor areas of an image sensor of the multi-aperture imaging device, as well as with a second arrangement of optical channels for projecting at least a part of of the total field of view on a second image sensor area of the image sensor.
IMAGE CAPTURE FOR VIRTUAL REALITY DISPLAYS
A light-field camera system such as a tiled camera array may be used to capture a light-field of an environment. The tiled camera array may be a tiered camera array with a first plurality of cameras and a second plurality of cameras that are arranged more densely, but have lower resolution, than those of the first plurality of cameras. The first plurality of cameras may be interspersed among the second plurality of cameras. The first and second pluralities may cooperate to capture the light-field. According to one method, a subview may be captured by each camera of the first and second pluralities. Estimated world properties of the environment may be computed for each subview. A confidence map may be generated to indicate a level of confidence in the estimated world properties for each subview. The confidence maps and subviews may be used to generate a virtual view of the environment.

SAMPLE IMAGING VIA TWO-PASS LIGHT-FIELD RECONSTRUCTION
Methods and systems for sample imaging via two-pass light-field reconstruction. In an exemplary method, a light-field image of a sample may be captured in a light-field plane. The light-field image may be forward-projected computationally to each of a plurality of z-planes in object space to generate a set of forward-projected z-plane images. Backward-projections computationally to the light-field plane of the same xy-region in object space from each z-plane image may be compared with the light-field image, to determine a respective degree of correspondence between the backward-projected xy-region from each of the z-plane images and the light-field image. For each different xy-region, at least one of the forward-projected z-plane images may be selected to contribute data for the different xy-region in a 2D or 3D object-space image of the sample.
METHOD FOR OBTAINING A POSITION OF A MAIN LENS OPTICAL CENTER OF A PLENOPTIC CAMERA
A method is described for obtaining a position of a main lens optical center of a plenoptic camera. The plenoptic camera has a micro-lens array (MLA) positioned in front of a sensor, the main lens optical center position being defined in a referential relative to the sensor. Such method is remarkable in that it obtains, from a 4D raw light-field data of a monochromatic scene, a set of symmetry axes, each symmetry axis of the set being defined as a line associated with a micro-image, the line passing in the neighborhood of the micro-image center coordinates of the micro-image it is associated with, and in the neighborhood of the brightest pixel in the micro-image it is associated with, the set comprising at least two symmetry axes and determines the position of the main lens optical center according to at least two symmetry axes of the set.

The visual output displayed on the display device varies as a function of the viewing position information.
Image processing apparatus and image processing method
An image processing apparatus generates, from the captured image, a plurality of images, which respectively corresponds to ranges of individual subject distances. The apparatus then applies image processing to at least one of the images in accordance with an instruction to change the shooting distance and field angle of the captured image, and generates a combined image that corresponds to the changed shooting distance and field angle. The image processing is applied to at least one of the images such that the size of a primary image in the combined image after changing the shooting distance and the field angle does not change.
