摘要： Systems and methods are provided for detecting objects of an object class, such as faces, in an image sensor. In some embodiments, the image sensor can include a detector with an image buffer. The image buffer can store image data in raster order. The detector can read the data out in Z order to perform object detection. The image data can then compute feature responses using the Z-ordered image data and determine whether any objects of the object class are present based on the feature responses. In some embodiments, the detector can downscale the image data while the object detection is performed and use the downscaled image data to continue the detection process. In some embodiments, the image data can perform detection even if the image is rotated.

摘要： A method of scanning a scene using an image sensor includes (a) dividing the scene into multiple first portions; and scanning a first portion for presence of objects in an object class. The method further includes continuing the scanning of the multiple first portions for presence of other objects in the scene. The method also selects a second portion of the scene, in response to detecting an object in the first portion; and then tracking the object in the selected second portion. The second portion of the scene is selected based on estimating motion of the object detected in the first portion, so that it may still be located in the second portion.

摘要： A self calibrating stereo camera includes first and second spatial transform engines for directly receiving first and second images, respectively, of an object. The first and second spatial transform engines are coupled to a stereo display for displaying a fused object in stereo. A calibration module is coupled to the first and second spatial transform engines for aligning the first and second images, prior to display to a viewer. The first and second point extracting modules, respectively, receive the first and second images for extracting interest points from each image. A matching points module is coupled to the first and second point extracting modules for matching the interest points extracted by the first and second point extracting modules. The calibration module determines alignment error between the first and second images, in response to the interest point matches calculated by the matching points module.

摘要： Systems and methods are provided for detecting an object of object class, such as faces, in an image sensor. In some embodiments, the image sensor can provide a scan sequence that scans a scene over multiple time intervals. The image sensor can scan, in succession, portions of a scene, where each of the portions covers a different amount or location of the scene. This way, the scanned portions can be saved in an image buffer that is sized significantly smaller than an entire frame. In some embodiments, when the image sensor detects the presence of an object of the object class, the image sensor can store positional information (e.g., location and size of the object) in a region of interest buffer. The image sensor can output the positional information to aid an electronic device, such as a camera, perform various functions, such as automatic exposure and color balancing.
摘要翻译：系统和方法被提供用于在图像传感器中检测对象类的对象，例如面部。在一些实施例中，图像传感器可以提供在多个时间间隔上扫描场景的扫描序列。图像传感器可以连续地扫描场景的各部分，其中每个部分覆盖场景的不同量或位置。这样，扫描的部分可以保存在尺寸明显小于整个帧的图像缓冲器中。在一些实施例中，当图像传感器检测到对象类别的对象的存在时，图像传感器可以将位置信息（例如，对象的位置和大小）存储在感兴趣区域缓冲器中。图像传感器可以输出位置信息以帮助诸如照相机的电子设备执行各种功能，例如自动曝光和色彩平衡。
