Image Processing: Color Extraction
Author: Keyence
Posted: 05/14/2013
This white paper introduces the idea of image processing from the basics. The topic covered in this document is color extraction, which reduces the amount of data that must be processed. To achieve both high performance and speed, it is important to select the right method of extracting color information for the specific target.

Feedback Sensors Keep Servo Motors on Target

Fundamentally a servo system can perform no more accurately than the accuracy of the feedback device controlling it. In addition, errors in speed or position can be introduced into the system by the less than perfect mechanisms that transfer the motor power to the load. Environmental factors like electrical noise or temperature  may also introduce positioning errors. Sometimes the errors are acceptable. More frequently, however, they are not. After all, servo motors can be expensive, and the expectation is that they will be the most reliable and accurate of all positioning devices.

When it comes to high-performance servo applications, feedback devices fall into several different categories. In this white paper, learn how each offers unique advantages and disadvantages, both electrical and mechanical, which make one better suited for a particular application than another.
