This chapter addresses adaptive parameter estimation for a general linear model illustrated by a parametrized linear time‐invariant system in either continuous or discrete time. Detailed design and analysis of a normalized gradient algorithm and a normalized least‐squares algorithm in either continuous or discrete time are given, including. Motion estimation is the process of determining motion vectors that describe the transformation from one 2D image to another; usually from adjacent frames in a video sequence. It is an ill-posed problem as the motion is in three dimensions but the images are a projection of the 3D scene onto a 2D plane. The motion vectors may relate to the whole image or specific parts, such as rectangular blocks, arbitrary .
Two adaptive filter based motion estimation algorithms are presented in this paper to estimate reference heartbeat signal, namely one step adaptive filter based motion estimation algorithm and a generalized adaptive filter based motion estimation algorithm. realizes our model-based motion estimation approach. In Section 4, we present our model-based adaptive motion estimation algorithm using Renyi’s entropy. The unique property of our algorithm is its low complexity. Therefore, in Section 5, we analyze the complexity of the encoder and decoder using our scheme and compare it with existing schemes.

Motion estimation is a critical problem in the design of a video encoder. Existing motion estimation techniques do not effectively utilize the past knowledge in motion prediction, leading to inefficiency in computation. To address this problem, we proposed an adaptive model-based motion estimation algorithm using Renyi’s entropy.

Abstract: This paper proposes a new method of calculating a matching metric for motion estimation. The proposed method splits the information in the source images into multiple scale and orientation subbands, reduces the subband values to a binary representation via an adaptive thresholding algorithm, and uses mutual information to model the similarity of corresponding square windows in each image.
