Abstract: Embodiments of the present disclosure provide techniques and configurations for an optoelectronic three-dimensional object acquisition assembly configured to correct image distortions. In one instance, the assembly may comprise a first device configured to project a light pattern on an object at a determined angle; a second device configured to capture a first image of the object illuminated with the projected light pattern; a third device configured to capture a second image of the object; and a controller coupled to the first, second, and third devices and configured to reconstruct an image of the object from geometric parameters of the object obtained from the first image, and to correct distortions in the reconstructed image caused by a variation of the determined angle of the light pattern projection, based at least in part on the first and second images of the object. Other embodiments may be described and/or claimed.

Abstract: A mechanism is described for facilitating depth image dequantization at computing devices according to one embodiment. A method of embodiments, as described herein, includes detecting a digital image of an object, the digital image including pixels having associated pixel values contaminated by noise, and side information pertaining to confidence of a value acquired in each pixel. The method may further include measuring characteristics of noise in each pixel of the digital image, and a plurality of weights relating to one or more of the pixel values, the side information, and the noise characteristics. The method may further include computing a smart filter based on a combination of the plurality of weights, applying the smart filter to filter the digital image by reducing the noise in the digital image, and outputting the filtered digital image.

Abstract: A mechanism is described for facilitating management of image noise in digital images using a smart noise management filter according to one embodiment. A method of embodiments, as described herein, includes detecting a digital image of an object, where detecting further includes detecting a pattern signal associated with the digital image. The method may further include measuring a spread function relating to at least one of the digital image and an imaging system of a computing device, where measuring further includes determining deconvolution of the spread function, and where measuring further includes computing a pre-shaping filter based on the deconvolution of the spread function. The method may further include executing the pre-shaping filter to apply the pattern signal to the deconvolution of the spread function to obtain a pre-shaped projection pattern of the digital image.
