Visual tracking and measurement is one of the most important tasks in computer vision and finds applications in traffic surveillance, vision-guided mobile robots, etc. In this paper, a binocular vision system is used to achieve the visual servoing, mimicking the movements of human eyes. First, a robust scheme, which combines adaptive Background Subtraction (BS) and Camshift algorithms, is proposed to detect and track a moving object. Then, we discuss the problems of camera parameter calibration and position measurement of moving objects. A new approach is introduced to realise the extrinsic parameter calibration of a pan-tilt camera, providing successful tracking and accurate measurement of a moving target, even as it is outside the view of the camera. Numerous experiments have been done on the binocular vision system of a humanoid mobile platform, and the results show that the proposed approaches work very well.

Eight Ways to Avoid Catching and Spreading the Flu
WHAT’S AT STAKEEvery year, millions of workers are infected with a contagious respiratory illness: influenza, commonly known as the flu. Many workers who are sick with the flu refuse to let the illness prevent them from working, thinking they can “tough it out.” So they go to work with a reduced ability to work safely and productively, and they jeopardize the health of their co-workers. WHAT’S THE DANGERThe flu virus is easily spread, mainly through droplets made when someone who has the...
Antifreeze Windshield Washing Liquid
In cold season nonfreezing liquid for windshield washer along with gasoline are virtually the only consumable materials for a car. It seems impossible to not use this product, because it allows the driver to maintain visibility of the traffic situation and helps reduce the number of car accidents. Antifreeze is used in all cars regardless of their brand and manufacture year. The use of summer liquid or water in winter is a reckless step. In this article we will not focus on all the positive qualities of windshield...

Tips to maintain your HPLC & UHPLC systems and columns
Recently, Ade Kujore (Cecil Instruments), Tracie Brombos (GenTech Scientific) and I were asked by Angelo De Palma, a well-respected writer for Lab Manager magazine, to contribute to an article about maintaining and caring about your laboratory instruments. Here are my tips/best practices for column and HPLC/UHPC/UPLC system maintenance. Maintaining your LC columns Proper storage of HPLC columns will increase longevity and performance. For long-term storage, it is best to follow manufacturer’s recommendatio...
Wash Water Questions and Answers
When the subject of Wash Water Recycling comes up there are many questions that can arise. The following are a few that are frequently asked are: Will it have an odor? What will its’ clarity be? How much is recycled? The above questions seem very basic but can at times create a complex response because of the specific application. Let’s explore each question independently. Question: Will it have an odor? Response: The wash water being processed through the GSMS or HSMS Series has no odor...
