Description: The motion within an image region is modeled using an affine transformation. Affine motion parameters are estimated using a coarse-to-fine gradient-based method. The approach is implemented using a robust M-estimation technique to make the computation insensitive to outliers which result from multiple motions. The approach estimates a dominant motion in the scene and detects points which are not moving consistently with the dominant motion. Additional motions are optionally estimated using these outliers.

Description: Real-Time Facial Feature Point Extraction-Localization of facial feature points is an important step for many subsequent facial image analysis tasks. In this paper, we proposed a new coarse-to-fine method for extracting 20 facial feature points from image sequences. In particular, the Viola-Jones face detection method is extended to detect small-scale facial components with wide shape variations, and linear Kalman filters are used to smoothly track the feature points by handling detection errors and head rotations. The proposed method achieved higher than 90 detection rate when tested on the BioID face database and the FG-NET facial expression database. Moreover, our method shows robust performance against the variation of face resolutions and facial expressions.

Description: The book describes a range of deformable template models, from coarse sparse models involving discrete, fast computations to more finely detailed models based on continuum formulations, involving intensive optimization. Each model is defined in terms of a subset of points on a reference grid (the template), a set of admissible instantiations of these points (deformations), and a statistical model for the data given a particular instantiation of the object present in the image. A recurring theme is a coarse to fine approach to the solution of vision problems. The book provides detailed descriptions of the algorithms used as well as the code, and the software and data sets are available on the Web.

Description: This algorithm was introduced by Koga et al in 1981. It became very popular because of its simplicity and also robust and near optimal performance. It searches for the best motion vectors in a coarse to fine search pattern. The algorithm may be described as:
Step 1: An initial step size is picked. Eight blocks at a distance of step size from the centre (around the centre block) are picked for comparison.
Step 2: The step size is halved. The centre is moved to the point with the minimum distortion.-This algorithm was introduced by Koga et al in 1981.

Description: 用多分辨率配准方法执行图像配准更加广泛地用在改进速度、精确度和自动化程度上。
基本的思想是图像有较少的像素的地方就用粗糙的比例。粗糙水平的空间映射被用来在接下
来的较好的图像中初始化配准。重复这个过程直到达到最好的比例范围。从粗糙到平滑的策
略极大地改进了配准的成功率，并通过消除粗糙比例时的局部噪声达到提高自动化的目的。-Performing image registration using a multi-resolution approach is widely used to improve
speed, accuracy and robustness. The basic idea is that registration is first performed at a coarse
scale where the images have fewer pixels. The spatial mapping determined at the coarse level is
then used to initialize registration at the next finer scale. This process is repeated until it reaches
the finest possible scale. This coarse-to-fine strategy greatly improve the registration success
rate and also increases robustness by eliminating local optima at coarser scales.
