The generation and development of digital image processing are mainly affected by three factors: first, the development of computers; [3] second, the development of mathematics (especially the creation and improvement of discrete mathematics theory); [4] and third, the demand for a wide range of applications in environment, agriculture ...
An important development in digital image compression technology was the discrete cosine transform (DCT). [16] DCT compression is used in JPEG, which was introduced by the Joint Photographic Experts Group in 1992. [17] JPEG compresses images down to much smaller file sizes, and has become the most widely used image file format on the Internet. [18]
Scanography is a related process in which digital photos are created using a scanner. New technology in digital cameras and computer editing affects the way photographic images are now perceived. The ability to create and fabricate realistic imagery digitally—as opposed to untouched photos—changes the audience's perception of "truth" in ...
Computer graphics is a core technology in digital photography, film, video games, digital art, cell phone and computer displays, and many specialized applications. A great deal of specialized hardware and software has been developed, with the displays of most devices being driven by computer graphics hardware .
This was the inspiration for the development of the wearable computer in the 1970s and early 1980s. Computational photography was inspired by the work of Charles Wyckoff , and thus computational photography datasets (e.g. differently exposed pictures of the same subject matter that are taken in order to make a single composite image) are ...
It had a TFT liquid-crystal display (LCD) and stored up to 20 digital photos at 350,000-pixel resolution. However, it could not send the resulting image over the telephone function but required a computer connection to access photos. [29] The first mass-market camera phone was the J-SH04, a Sharp J-Phone model sold in Japan in November 2000.
Computer-generated imagery (CGI) is a specific-technology or application of computer graphics for creating or improving images in art, printed media, simulators, videos and video games. These images are either static (i.e. still images ) or dynamic (i.e. moving images).
Digital Image Analysis or Computer Image Analysis is when a computer or electrical device automatically studies an image to obtain useful information from it. Note that the device is often a computer but may also be an electrical circuit, a digital camera or a mobile phone.
