چکیده

We propose a novel automatic tracking system capable of tracking fast-moving, small objects under extreme conditions by using high-speed visual feedback for assessing sperm chemotaxis. The system shows remarkable performance and versatility, good enough for practical use in biology. Experimental results showed that we successfully achieved continuous stable tracking of swimming ascidian spermatozoa with quality sufficient for assessing sperm motility, indicating the feasibility of our system to tracking almost any type of cell.

Robust Optimal Speed Tracking Control of a Current Sensorless Synchronous Reluctance Motor Drive using a New Sliding Mode Controller

This paper describes the robust optimal incremental motion control of a current  sensorless synchronous reluctance motor (SynRM), which can be specified by any desired speed profile. The control scheme is a combination of conventional linear quadratic (LQ) feedback control method and sliding mode control (SMC). A novel sliding switching surface is employed first, that makes the states of the Sy...

Visual Tracking using Kernel Projected Measurement and Log-Polar Transformation

Visual Servoing is generally contained of control and feature tracking. Study of previous methods shows that no attempt has been made to optimize these two parts together. In kernel based visual servoing method, the main objective is to combine and optimize these two parts together and to make an entire control loop. This main target is accomplished by using Lyapanov theory. A Lyapanov candidat...

3D tracking using two high-speed vision systems

When considering real-world applications of robot control with visual servoing, both 3D information and a high feedback rate are required. We have developed a 3D target tracking system with a 1ms feedback rate using two high-speed vision systems called Column Parallel Vision (CPV) systems. To obtain 3D information, such as position, orientation, and shape parameters of the target object, a feat...

Microorganism Tracking Microscope System

Continuous observation of individual motile microorganisms is difficult, since their swimming speed is fast compared with their diameters. In fact, some bacteria can swim as fast as 50 diameters/s [1]. At this speed, microorganisms can quickly go out of the range of static measurement instruments, such as the field of view of optical microscopes. This problem can be solved by tracking the micro...
