Abstract

In an example embodiment a method, apparatus and computer program product are provided. The method includes accessing feature points in a first frame of a content, and aligning a second frame to the first frame based on determining a transformation matrix between the second frame and the first frame based on matching the feature points in the first frame with a corresponding feature points in the second frame. The method further includes aligning at least one subsequent frame from the second frame to the first frame by generating a modified first frame based on a transformation matrix between a preceding frame of a subsequent frame and the first frame, and determining a transformation matrix between the subsequent frame and the first frame based on matching a set of feature points in the modified feature points with corresponding feature points in the subsequent frame.

Description

technical field [0001] Various embodiments generally relate to methods, apparatus, and computer program products for frame alignment. Background technique [0002] Recently, there has been more focus on a form of media production that bridges the gap between images and video known as motion pictures or animated images. In an animated image, part of the frame is in motion while the background is still. From a consumer's point of view, the ability to freeze major parts of the picture and only make the salient parts of the video come alive creates a very engaging and creative user experience on the device. One of the major challenges in generating animated images from video captured by a user on a device such as a mobile phone is the problem of hand shaking while capturing the video. To remove the global motion introduced in this way, the video needs to be stabilized or aligned so that the effect of hand motion is counteracted. Contents of the invention [0003] Various as...
