4) Introduction to Surface Inspection Technology
l General procedure of surface inspection system
The surface inspection system is actually a machine vision system. Its flow is:
l High-precision positioning registration algorithm
a. The role of positioning algorithm in machine vision system
â– Image feature extraction.
â– Mainly relative position information, including rotation angle, horizontal and vertical offsets, provides information for various subsequent detection algorithms and belongs to the bottom layer of the system. Offset color, color mixing, wiring, overprinting, printing and other detection algorithms in off-line offset inspection systems all require the use of positioning module data.
â– Linear simulation of nonlinear deformations. Due to the non-linear deformation of the paper, only a sufficient number of positioning points can realistically simulate the nonlinear deformation in the line segment.
b. Classification of positioning algorithms
â– Use image grayscale features for positioning
â– Use image geometry for positioning
â– Use image space domain information for positioning
l Blob cluster analysis algorithm
a.Blob analysis algorithm
â– Blob analysis algorithms, also known as speckle analysis algorithms, are often used to extract and classify image features from a target image.
â– By analyzing the graphical characteristics of the Blob unit, a simple pattern of gray information can be rapidly converted into the shape information of the pattern, including the graphic center of mass, the area of â€‹â€‹the graph, the perimeter of the graph, the minimum rectangle of the graph, and other graphic information.
â– The Blob analysis algorithm plays an important role in the surface detection. It can judge the true defects and the false defects according to different graphic characteristics.
â– Blob analysis algorithms can also be used in the field of particle counting.
b. Blob analysis step
i. Blob image segmentation
â– Fixed Threshold
Suitable for images with high contrast and good background consistency.
â– Variable Threshold
Segmentation is performed using statistical information such as minimum mean, maximum mean, and mean squared error. Suitable for some images with poor contrast and consistency.
Ii. Blob feature extraction
â– After image segmentation, the grayscale information of the image can be converted into a Blob message queue through the Blob feature extraction process.
â– According to the requirements of the surface quality detection application, targeted algorithm can be used to extract more Blob shape information.
c. Typical Blob Features
The typical Blob features are: ratio of Blob area to circumscribed rectangle area, Blob extension rate, and the long axis angle of the minimum bounding ellipse.
Even the industrial industry has found their way into tubes. Products such as lube are increasingly being packaged in plastic tubes which allows for clean and accurate usage. Precision application can also be enhanced with our unique long nozzle twist cap. "GY tubes- A job well done"

Tubes - Printing
We have three different print methods you can choose from depending on the design of your artwork and the way you would like it displayed on your tubes. We are able to print with all three methods on one tube so do not feel like you have choose just one for your design.
Offset Print: Up to 6 colors. Use of CMYK/4-Color Process. Gradient Screens are acceptable. Feels like the ink is impregnated on the tubes and takes on the finish you have chosen for your tubes.
Silk Screen: Up to 3 colors. When you run your fingers over the art on the tube it is raised up and will always remain glossy, even on a matte finish tube.
Hot Stamping of Foils: Up to 2 colors. Slight feel to the touch. Finish remains glossy with a metallic sheen.
When it comes to health we don't take any chances. Tamper seals are available to protect your product. In addition GY Tube now also offers our very innovative tamper evident flip top cap which helps further guarantee the safety of your product. "GY tubes are worth your health"
In this fashion-driven market, the appearance of your packaging takes precedence. With our high-end equipment GY's abilities in the decoration of your packaging is endless. Your attractive packaging will appeal to even the hard to please consumer. "GY tubes has got you covered"
Plastic tubes have become widely used for the Toothpaste Industries. Our high quality 5 layer, barrier coated co-extruded tubes have out-performed laminate tubes in the stability testing of aggressive ingredients found in Toothpastes such as fluoride. "GY tubes will definitely make you smile"
Our body is our self image and we take great care to maintain it by using only the best of products for our skin and hair. To make certain that your product stands out among the others let Vista help you design the most eye-catching packaging on the store shelves. "GY tubes is hair for you"
We understands the importance of hygiene, when it comes to the packaging of your food. Our facility is FDA approved and all our tubes are produced in accordance with their requirements. We ensure proper sanitary conditions throughout production. "GY tubes are fit to eat"
