are based on western theories and relevant concepts.
The treasure TCM has not yet been carried forward
on mobile platforms.
Chinese civilization has a long history. TCM
has spread and developed with the process of
history. It has formed a set of solid and unique
TCM theory and clinical application system.
Compared with western medicine, TCM emphasizes
people-oriented. TCM comprehensively understands
various physical features of the human body and
systematically grasps the relevant information of the
occurrence and development. Thus TCM can guide
clinical treatment and health care. TCM forms a
multilevel and multi-angle complementarity with
the diagnosis and treatment system of western
medicine, [2], [3].
2.2.2 Tight Relationship with the Internet
Emerging industries formed by the "Internet +" and
integration and upgrading with traditional industries
will be the important economic growth point of
expanding consumption and promoting
employment. From the perspective of industrial
structure, "Internet +" drives the upgrading of
industrial structure by forming a great economic
vitality and wealth effect, rapid development of
emerging information industry, and fusion
optimization of internet technology and traditional
industries. Internet can reduce the transmission cost
of information to a very low level. After receiving a
large amount of information, the degree of
information asymmetry between consumers and
producers has decreased significantly. The choice
range of residents' consumption has been greatly
expanded. Residents can use social mobile networks
to unite. They begin to participate in all commercial
links of production and consumption after solving
the problems of dispersion and isolation to
interconnection. They can truly become the leading
force of production and consumption. [4], so the
system is developed based on the Internet.
2.3 The Product Line of the CTM Tongue
Image Consulting System
2.3.1 Tongue Image APP
2.3.1.1 Basic Principle
The diagnostic technology of traditional TCM is
well known around the world. The four diagnostic
methods including looking, listening, questioning,
and feeling pulse have been widely used for
thousands of years. Tongue diagnosis is an
important step to look for diagnosis. It is an
effective diagnosis method for the doctor to
understand the pathological changes in patients by
observation of the tongue. According to TCM
theory, the tongue is a mirror of the body's internal
physiology. The tongue can fully and flexibly
reflect the internal changes of the the internal organs
of human viscera. Therefore, tongue diagnosis has
become one of the important tools of TCM
diagnosis, [5].
Western medical research has also noticed that
tongue images can reflect physical conditions. The
British used a three-color colorimeter to check the
tongue of the patient in the 1970s. They believe that
any tongue containing blue is abnormal. However,
the diagnosis of the tongue has always been
analyzed and judged by subjective visual
observation. And doctors use language to
summarize the disease, lack of automatic and
quantitative objective measurement. Tongue
diagnosis is easily affected by external conditions
such as light, angle, and other factors, etc. Also, the
interference of doctors' human factors (such as
knowledge level, clinical diagnosis experience, etc.)
can affect tongue diagnosis. All these restrict the
wider application and modernization of tongue
diagnosis. With the continuous development and
technical promotion of the modernization of TCM
in recent years, people have higher requirements for
the quantification and objectification of tongue
diagnosis. The objective study of tongue image has
started since the 1990s. Researchers have made
many valuable explorations on extraction of tongue
image features and tongue image analysis, [6].
With rapid development of artificial intelligence
(AI) in past a few years, more and more AI
technologies combine with traditional applications.
Like tongue diagnosis, TCM doctors can examine
diseases of patients through tongue color, shape, and
texture. Many AI specialists want to simulate the
process that TCM doctors’ examination based on AI
technologies. Currently, most methods are focused
on comparison of the tongue photos themselves, [7].
These research methods propose higher
requirements for taking tongue photos.
On methodology our technology achieves a
breakthrough. The deep learning technology of the
convolutional neural network(CNN) is applied.
Through PCA Net model, tongue photos can be
analyzed starting from the underlying pixels for
feature purification and analysis. Because taking
tongue photos comes from mobile phone, the
method provides greater redundancy on different
mobile brand, photo color, taking angles etc. The
research method is pioneering.
