Image analysis method - Method of measuring irregular leaf area of ​​ragweed. According to experts, this is a “plant killer†whose destructive power is equivalent to water hyacinth and Spartina alterniflora, and it will also harm human health. The country will use ragweed as a control month in May of each year. It is hoped that the loss will be reduced through the prevention of ragweed. The ragweed leaves will have an irregular shape with feathery cracks. Understanding the area of ​​the leaves will allow us to understand ragweed Light energy utilization, moisture evaporation, dry matter accumulation and other physiological processes can be used to take appropriate measures. The fastest method of measuring the leaf area of ​​ragweed is to use a portable leaf area meter to perform operations, and it can also be used by The image analysis method was used to calculate the ragweed leaf area.
The method of using the image processing method is to use a digital camera to photograph the blade first, or to use a scanner to scan the blade and use the Photoshop software to operate. The steps of the Photoshop software are: open the blade Image, use the "magic bar" tool to select the part of the picture, and then open the "image" in the menu, select the "histogram" option, record the "total pixels" value in the display parameters, calculate the leaf area according to the image resolution. Since the number of pixels per unit length is the resolution of the image, if the size of each pixel composing the image of the blade is known, the blade can be calculated from the total pixels. There are certain errors in the measurement using this method, and the operation is more troublesome at the same time. There is a certain similarity between the use of a portable leaf area meter and the accuracy of a small area leaf area measurement. However, there is a certain error in the determination of the leaf area of ​​a large area plant, and it will also be time-consuming. Suitable for promotion.
Small area measurement, whether it is image processing method or portable leaf area meter method is relatively good, but the area of ​​the alternative method to conduct measurements will be more accurate, the most important is the comparative rapid.

This classification mainly includes the aluminum low-pressure casting Machinery Parts using in many area.
From the part, we can easily find that the parts have a lot of features of big cavities, so the part will have big potential risk of mold release problem, if so, the part may happen to be deform, sticking to the mold etc, especially when the part sticking to the mold, if no clear in time, while next shot, the mold may be destroyed while clamping.
