Object recognition software needs no training

Object recognition software needs no training: "Typically, object recognition algorithms need to be 'trained' using digital images in which objects have been outlined and labeled by hand. By looking at a million pictures of cars labeled 'car,' an algorithm can learn to recognize features shared by images of cars. The problem is that for every new class of objects — trees, buildings, telephone poles — the algorithm has to be trained all over again. But Antonio Torralba and Computer Science and his colleagues at MIT have developed an object recognition system that doesn't require any training. Nonetheless, it still identifies objects with 50 percent greater accuracy than the best prior algorithm. The system uses a modified version of a so-called motion estimation algorithm, a type of algorithm common in video processing. Since consecutive frames of video usually change very little, data compression schemes often store the unchanging aspects of a scene once, updating only the positions of moving objects. The motion estimation algorithm determines which objects have moved from one frame to the next. In a video, that's usually fairly easy to do: most objects don't move very far in one-30th of a second. Nor does the algorithm need to know what the object is; it just has to recognize, say, corners and edges, and how their appearance typically changes under different perspectives.

Color Sensors Press Release

TOLEDO — Industrial Vision Components .com has partnered with SensoPart, Inc. to offer a full line of color sensors and contrast sensors designed to help manufacturers control monitor and control their manufacturing processes or to help verify proper assembly of complex products. SensoPart’s Sensor Innovation Prize winning sensors offer a wide range of features and functions, allowing manufacturers the ability to select the unique sensor that is ideal for every application.

Our full range of color and contrast sensors available from Industrial Vision Components .com provides manufacturers with the right sensor at the right price. From top to bottom, SensoPart’s award winning sensors provide outstanding reliability and industry leading price/performance value. Our family of sensors includes:

FT 50 C Series - Versatile and full featured, the FT50 C operates with white light and was especially designed for on-line color detection in industrial operations and processes. Thanks to a special patented lens, the sensor also offers a unique depth of field, enabling it to reliably detect even moving and vibrating objects making it ideal for the automation of all industrial operations and processes, where the color of an object or a colored marking serves as criterion for detection or segmentation.

FA 45 Series - The FA-45 Color Sensing Vision Sensor is a fast and economic solution to inspection applications without experience in image processing. Ideal for checking color and function of status lights, checking seven-segment LED and LCD displays, detecting presence of color components, verifying colors for cables, cable harnesses and connectors, and detecting the degree of browning on food. The FA-45 is the first cost-effective automation solution for the functional check of colored illuminated displays. Up to 32 individually coded colors, easy set up.

FT 20 RL Series - FT 20 RL Contrast Sensors are ideal for precise detection of small printing marks. The FT 20 RL provides a scanning range 40 mm to 150 mm and features teach-in set up with a key lock to prevent tampering.

FL 64-1 Series – SensoPart’s FL 64-1 C Color Sensor is a DIN rail mounted, fiber-optic color sensor that features 3 light sources (RGB), 1 color channel, timer function, and a working range of 5 to 10 mm.

Using a C-Mount Lens with a CS-Mount Camera

A Machine Vision FAQ:
Can I use a C-Mount Lens with my CS-Mount Camera?

Yes, A C-Mount lens can be used with a CS-Mount Camera with the use of a 5mm spacer.

The C-mount specification requires a 17.5mm distance from the lens mounting surface to focus on the cameras sensor (CCD or CMOS). The CS-mount specifications requires a 12.5mm distance from the lens mounting surface to focus on the cameras sensor. By adding the 5mm spacer to a CS-Mount Camera you in effect produce the required 17.5mm focal distance that all C-Mount Lenses are designed for.

Important note: CS-Mount Lenses CANNOT be used with C-Mount Cameras!

New Machine Vision Telecentric Lens for gauging applications
Press Release:http://news.thomasnet.com/fullstory/821297

What is a Telecentric Lens?
Well if you read the standard definitions you will hear alot of optical technical "mumbo jumbo" of which the information is true but doesn't do most application engineers much good.
So here is a basic description...

Telecentric lenses, unlike conventional lenses, only accept parallel cones of light. This means objects maintain there image size regardless of their distance from the lens. This eliminates the perspective effect noticeable in applications that use standard lenses.

Telecentric lenses are ideal for gauging appliations because they provide a true "caliper" measurement. While improving accuracy they also are less affected by part misalighnment. Not only can telecentric lenses eliminate the perspective effect but high quality telecentrics such as Industrial Vision Components' Elite Series Telecentric Lenses have an extremely low distortion providing for accurate measurements in any region of the Field of View (FOV).
