摘要： Aspects relate to a method of generating a high-resolution image containing depth information of an object. In one aspect, the method includes downsampling a first reference image and a second reference image from a first resolution to a second resolution, wherein the first resolution is higher than the second resolution, and wherein the first reference image and the second reference image comprising a stereo image pair. The method further includes generating a depth map at the second resolution based on global minimization techniques, using the downsampled stereo image pair. The method also includes upsampling the depth map from the second resolution to the first resolution and using a guided filter to align contours of the upsampled depth map to contours of the first reference image.

摘要： An interactive display, including a cover glass having a front surface that includes a viewing area provides an input/output (I/O) interface for a user of an electronic device. An arrangement includes a processor, a light source, and a camera disposed outside the periphery of the viewing area coplanar with or behind the cover glass. The camera receives scattered light resulting from interaction, with an object, of light outputted from the interactive display, the outputted light being received by the cover glass from the object and directed toward the camera. The processor determines, from image data output by the camera, an azimuthal angle of the object with respect to an optical axis of the camera and/or a distance of the object from the camera.

摘要： Systems and method for generating depth maps using active sensing technology, for scenes with moving objects, is disclosed. One aspect provides for a method that includes estimating areas in adjacent frames that correspond to a moving object by generating a probability map for each received frame, the probability map comprising a probability value at each pixel. The method also includes computing a convex temporal average map using a plurality of the reflected structured light frames including at least the prior frame received at time t−1, the received frame received at time t, and the next frame received at time t+1, the value at each pixel of the convex temporal average map weighted and normalized by the probability map at each pixel at each time. The method also includes determining the codewords at each pixel in the convex temporal average map, and generating a depth map from the determined codewords.

摘要： Certain aspects relate to systems and techniques for performing local intensity equalization on images in a set of images exhibiting local intensity variations. For example, the local intensity equalization can be used to perform accurate region matching and alignment of the images. The images can be partitioned into regions of pixel blocks, for instance based on location, shape, and size of identified keypoints in the images. Regions depicting the same feature in the images can be equalized with respect to intensity. Region matching based on the keypoints in the intensity-equalized regions can be performed with accuracy even in images captured by asymmetric sensors or exhibiting spatially varying intensity.

摘要： Aspects of the present disclosure relate to systems and methods for determining a resampler for resampling or converting non-Bayer patter color filter array image data to Bayer pattern image data. An example device may include a camera having an image sensor with a non-Bayer pattern color filter array configured to capture non-Bayer pattern image data for an image. The example device also may include a memory and a processor coupled to the memory. The processor may be configured to receive the non-Bayer pattern image data from the image sensor, divide the non-Bayer pattern image data into portions, determine a sampling filter corresponding to the portions, and determine, based on the determined sampling filter, a resampler for converting non-Bayer pattern image data to Bayer-pattern image data.
