In this paper, High Accuracy Optical Flow (HAOF) based future image frames generator model is proposed. The aim of this work is to develop a framework which is capable of predicting the future image frames for any given sequence of images. The requirement is to predict large number of image frames with better clarity and better accuracy. In the first step, the vertical and horizontal components of flow velocities of the intensities at each pixel positions are estimated using High Accuracy Optical Flow (HAOF) algorithm. The estimated flow velocities in all the image frames at all the pixel positions are then modeled using separate Artificial Neural Networks (ANN). The trained models are used to predict the flow velocities of intensities at all the pixel positions in the future image frames. The intensities at all the pixel positions are mapped to new positions by using the velocities predicted by the model. The concept of Bilinear Interpolation is used to obtain predicted images from the new positions of intensities. The quality of the predicted image frames is evaluated by using Canny Edge Detection based Image Comparison Metric (CIM) and Mean Structural Similarity Index Measure (MSSIM). The predictor model is simulated by applying it on the two image sequences-an image sequence of a fighter jet landing over the navy deck, and another image sequence of a train moving on a bridge. The proposed framework is found to give promising results with better clarity and better accuracy.
