An Accommodating Edge Follower
نویسندگان
چکیده
We describe an operational program that l o cates objects in a television image and traces their edges. The program accommodates the te levision camera, maximizing dynamic range during acquisit ion and sensi t iv i ty during t racing, to obtain the most appropriate image for each phase. If the trace routine loses an edge, various heurist ics diagnose the d i f f i c u l t y and tune both the camera and software to recover contrast at the point of d i f f i c u l t y . Experimental evidence of the effectiveness of accommodation is provided.

A New Algorithm for Motion Control of Leader-Follower Formation of Mobile Autonomous Agents
This paper presents a motion control strategy for a rigid and constraint consistent formation that can be modeled by a directed graph whose each vertex represents individual agent kinematics and each of directed edges represents distance constraints maintained by an agent, called follower, to its neighbouring agents. A rigid and constraint consistent graph is called persistent graph. A persiste...

متن کاملOn the dynamic stability of a flying vehicle under the follower and transversal forces
This paper deals with the problem of the instability regions of a free-free uniform Bernoulli beam consisting of two concentrated masses at the two free ends under the follower and transversal forces as a model for a space structure. The follower force is the model for the propulsion force and the transversal force is the controller force. The main aim of this study is to analyze the effects of...
متن کاملEmpirical Analysis of the Nature of Competition in a Laundry-Cleaning Additive Market
This study examines the nature of competition between the two leading brands of a national small size market by estimating shortand long-term competitive reactions via a Structural VAR (SVAR) model. The primary findings indicate how the two competitors react, which marketing instruments are used, and when competitive reactions affect crossand own-sales. The empirical results suggest that compet...
