Abstract: A method and system for generating three-dimensional (3D) model augmented related objects from a scene are provided. The method includes creating one or more 3D objects and placing the 3D objects into the 3D scene. Embodiments herein disclose methods and systems for generating 3D augmented reality (AR) objects from a scene. The method may capture an object from the scene, perform a coarse semantic segmentation on the identified object, derive connected contour, generate intermediate contour from at least one outer and inner contours, and configure three-dimensional mesh and texture mapping to generate a three-dimensional model of the captured object.

Abstract: A method for generating a high-dynamic-range (HDR) image using an imaging device is provided. The method includes capturing a long-exposure (LE) image, a short-exposure (SE) image, and an auto-exposure (AE) image of a scene, estimating motion information in the SE image and the LE image based on a reference image which is determined based on an image statistics parameter, aligning the SE image and the LE image using the motion information, generating a pixel-weight coefficient for each of the SE image, the LE image, and the AE image, generating an overlapped region mask corresponding to an overlapped region in each of the SE image, the LE image and the LE image, determining a modified pixel-weight coefficient in the overlapped region mask and correcting a brightness difference, and generating an HDR image from the SE image, the LE image and the AE image using the modified at least one pixel-weight coefficient.

Abstract: A method of selecting capture configuration based on scene analysis and an image capturing device are provided. The method includes analyzing by a processor, a scene currently being captured by an image capturing device having a plurality of imaging sensors, identifying a current image capturing mode of the image capturing device, setting at least one capture parameter for the plurality of the imaging sensors, upon determining that the at least one capture parameter of the current image capturing mode has to be changed, and determining a timing sequence for triggering the plurality of imaging sensors to capture a plurality of image frames based on the set at least one capture parameter.
