Transparency (graphic) Transparency in computer graphics is possible in a number of file formats. The term "transparency" is used in various ways by different people, but at its simplest there is "full transparency" i.e. something that is completely invisible. Only part of a graphic should be fully transparent, or there would be nothing to see.
A PNG file contains a single image in an extensible structure of chunks, encoding the basic pixels and other information such as textual comments and integrity checks documented in RFC 2083. [7] PNG files have the ".png" file extension and the "image/png" MIME media type. [8] PNG was published as an informational RFC 2083 in March 1997 and as ...
There are 4 basic choices for image file formats : SVG for simple diagrams (especially those that need to be scaled). JPEG for photographic images. GIF for animated images. PNG for everything else. While some formats offer multiple compression systems, in general the format and the compression system are tied together.
e. The waveform of a Gaussian white noise signal plotted on a graph. In signal processing, white noise is a random signal having equal intensity at different frequencies, giving it a constant power spectral density. [1] The term is used with this or similar meanings in many scientific and technical disciplines, including physics, acoustical ...
Image noise is random variation of brightness or color information in images, and is usually an aspect of electronic noise. It can be produced by the image sensor and circuitry of a scanner or digital camera. Image noise can also originate in film grain and in the unavoidable shot noise of an ideal photon detector. Image noise is an undesirable ...
Nostril. A nostril (or naris / ˈnɛərɪs /, pl.: nares / ˈnɛəriːz /) is either of the two orifices of the nose. They enable the entry and exit of air and other gasses through the nasal cavities. In birds and mammals, they contain branched bones or cartilages called turbinates, whose function is to warm air on inhalation and remove ...
The nasal septum contains bone and hyaline cartilage. [3] It is normally about 2 mm thick. [4] The nasal septum is composed of four structures: Maxillary bone (the crest) Perpendicular plate of ethmoid bone. Septal nasal cartilage (ie, quandrangular cartilage) Vomer bone. The lowest part of the septum is a narrow strip of bone that projects ...
Nasal hair or nose hair is the hair in the human nose. Adult humans have hair in the nostrils. Nasal hair functions include filtering foreign particles from entering the nasal cavity, and collecting moisture. [1] In support of the first function, the results of a 2011 study indicated that increased nasal hair density decreases the development ...
An "aquiline" nasal profile From parody nose classification Notes on Noses: "It indicates great decision, considerable Energy, Firmness, Absence of Refinement, and disregard for the bienseances of life". An aquiline nose (also called a Roman nose) is a human nose with a prominent bridge, giving it the appearance of being curved or slightly bent.
Other names. Deviated nasal septum (DNS) An MRI image showing a congenitally deviated nasal septum, bowed to the left between the eye sockets. Specialty. Otorhinolaryngology. Nasal septum deviation is a physical disorder of the nose, involving a displacement of the nasal septum. Some displacement is common, affecting 80% of people, mostly ...
