Mask Definition In Computer Science
The definition of a mask is something that conceals or disguises particularly a covering for the face.
Mask definition in computer science. In computer science a mask or bitmask is data that is used for bitwise operations particularly in a bit field using a mask multiple bits in a byte nibble word etc. Hashing data is a common practice in computer science and is used for several different purposes. For example consider the ip address 150 215 017 009 assuming this is part of a class b network the first two numbers 150 215 represent the class b network address and the second two numbers 017 009 identify a particular host on this. In microsoft windows a search mask is a string which may.
An ip address has two components the network address and the host address. Can be set either on off or inverted from on to off or vice versa in a single bitwise operation. I am fascinated by self driving cars. A hash function can be used to generate a value that can.
Values that do not conform to the mask cannot be entered. Hashing is a natural fit for cryptography because it masks the original data with another value. We will also look at how to implement mask r cnn in python and use it for our own images. A hash is a function that converts one value to another.
We will learn how mask r cnn works in a step by step manner. The standard protocol for transferring hypertext documents on the world wide web. Examples include cryptography compression checksum generation and data indexing. Subnet mask is a mask used to determine what subnet an ip address belongs to.
Noun an example of a mask is a face covering that children wear on halloween. The process of filtering is also known as convolving a mask with an image. Http definition hypertext transfer protocol. For example when defining a database field it is possible to assign a mask that indicates what sort of value the field should hold.
As this process is same of convolution so filter masks are also known as convolution masks. The general process of filtering and applying masks is consists of moving the filter mask from point to point in an image.
