Hui peopleThe Hui people (, Xiao'erjing: خُوِزُو, Хуэйзў, Xuejzw) are an East Asian ethnoreligious group predominantly composed of Chinese-speaking adherents of Islam. They are distributed throughout China, mainly in the northwestern provinces and in the Zhongyuan region. According to the 2010 census, China is home to approximately 10.5 million Hui people. Outside China, the 110,000 Dungan people of Kazakhstan and Kyrgyzstan are also considered part of the Hui ethnicity. The Hui have a distinct connection with Islamic culture.
NingxiaNingxia (nIN'Sɑː,ˈnɪŋˈʃjɑː; , ning2.xia4; alternately romanized as Ninghsia), officially the Ningxia Hui Autonomous Region, is an autonomous region in the northwest of the People's Republic of China. Formerly a province, Ningxia was incorporated into Gansu in 1954 but was later separated from Gansu in 1958 and reconstituted as an autonomous region for the Hui people, one of the 56 officially recognised nationalities of China. Twenty percent of China's Hui population lives in Ningxia.
Digital imagingDigital imaging or digital image acquisition is the creation of a digital representation of the visual characteristics of an object, such as a physical scene or the interior structure of an object. The term is often assumed to imply or include the , , , printing and display of such images. A key advantage of a , versus an analog image such as a film photograph, is the ability to digitally propagate copies of the original subject indefinitely without any loss of image quality.
Digital photographyDigital photography uses cameras containing arrays of electronic photodetectors interfaced to an analog-to-digital converter (ADC) to produce s focused by a lens, as opposed to an exposure on photographic film. The digitized image is stored as a ready for further digital processing, viewing, electronic publishing, or digital printing. It is a form of digital imaging based on gathering visible light (or for scientific instruments, light in various ranges of the electromagnetic spectrum).
ChangdeChangde ( chang2.de2) is a prefecture-level city in the northwest of Hunan province, People's Republic of China.

Digital signal processingDigital signal processing (DSP) is the use of digital processing, such as by computers or more specialized digital signal processors, to perform a wide variety of signal processing operations. The digital signals processed in this manner are a sequence of numbers that represent samples of a continuous variable in a domain such as time, space, or frequency. In digital electronics, a digital signal is represented as a pulse train, which is typically generated by the switching of a transistor.
