The MongoDB server can run on Linux, Windows, or OS X. It supports 32-bit and 64-bit applications. The default port is 27017. It is recommended to run on a 64-bit platform because MongoDB
The maximum file size supported when running in 32-Bit mode is 2 GB.
MongoDB stores data in files (the default path is/data/db) and uses memory ing files for management to improve efficie
Histogram is translated into a histogram. In computer image processing and visual technology, histogram is usually used for image matching to complete the track. For example, in the meanshift tracking algorithm, the histogram of the image is often used.
For the histogram Calculation of a grayscale image, you must first select the number of Bin (which can be called a slot in Chinese). For a grayscale image, the pixel range is usually [0-255], so the number of bin is 256, then we cycle the entire
