the object tracking, estimating 3D structure, video compression, video frame-rate conversion, and video surveillance system. The motion estimation technique forecast the apparent motion in time-varying images that obtained from the projection process of the realworld one 1). This motion occurs because of exact object motion, camera motion, an illumination change, and noise. The objective of the motion estimation technique is then to define a motion vector for each pixel or group of pixels in an image by using a specific calculation scheme. This calculation scheme involves the observed image and at least one of its neighbors. To the extent our observation, at least there are two types of motion estimation scheme that have been developed massively in recent years 1). The first is optical flow-based motion estimation that calculates the apparent motion vectors directly from two successive images. The calculation performs to solve the brightness constancy assumption between pixels in an image and each counterpart pixel in the following or previous image. The optical flow is very well known in computer vision applications. Some of them are mentioned above. The second one is block-based motion estimation. This concept directly calculates the similarity of each block of pixels in an image with each counterpart block of pixels in one of the following or previous images. Therefore, a motion vector can be obtained for each block. The blockbased motion estimation is very valuable in the video compression application. Besides the two major motion estimation concepts, other schemes have been developed in recent years 1). Among these, there is the global motion estimation which deals with a video sequence that contains camera motion. This motion then is modeled by parametric transformations. How to estimate the parametric transformations is known as the global motion estimation. This motion estimation is essential for the sports video content analysis, including zoom in and out applications. Another method is the motion estimation in the transform domain. This method utilizes correspondence between translations in the spatial domain with a change of phase of the Fourier coefficients. Therefore, the motion is estimated from a Abstract This paper aims to present an innovative design of motion estimation for sequential fisheye images. This design is an extended version of the original Lucas and Kanade's (LK) concept that used to design for calculating optical flow from general perspective images. The extended design consists of the LK concept and an additional self-improvement mechanism that automatically finds the maximum performance of the estimated motion. This extended scheme works much better than the original LK's idea or some block-based motion estimations. Moreover, to some extent, this proposed method is working extremely well to overcome some critical characteristics of the sequential fisheye images. These characteristics include distortion error on the fisheye image area, inconsistent brightness level, fluctuating numb...
