What is the segment in computer?

A network segment is a portion of a computer network. The nature and extent of a segment depends on the nature of the network and the device or devices used to interconnect end stations.

What is segment visibility in computer graphics?

Point-to-point visibility determines whether the line segment between two points is unoccluded, that is, the line segment has no intersection with an opaque object in the scene. Another visibility-along-a-line problem is determining the maximal free line segments on a given line.

What is called a segment?

segment. [ sĕg′mənt ] The portion of a line between any two of its points. The region bounded by an arc of a circle and the chord that connects the endpoints of the arc.

What is segment and segment table?

Segment Table – It maps two-dimensional Logical address into one-dimensional Physical address. It’s each table entry has: Base Address: It contains the starting physical address where the segments reside in memory. Limit: It specifies the length of the segment.

What is segmentation in DBMS?

In Operating Systems, Segmentation is a memory management technique in which the memory is divided into the variable size parts. Each part is known as a segment which can be allocated to a process. The details about each segment are stored in a table called a segment table.

Is segmentation still used?

Modern OSes “do not use” segmentation.

What do you mean by segment table?

The Segment table is a table that is temporarily kept in memory while it processing (OVRSEG) arcs. When OVRSEG is done, the information in the table is discarded. As it proceeds through the file from north to south, it has a scan line or band that stretches east/west along the file.

What is segmentation in multimedia?

Multimedia databases utilize segmentation for the storage and indexing of images and video. Image segmentation is used for object tracking in the new MPEG-7 video compression standard. Merging regions that are similar in color is a final means used for segmenting the image into even smaller regions.

What is segmentation job?

A segmentation job contains the job definition, security settings, and segment definitions used to generate contact or prospect lists. There are two types of segmentation jobs: Contact jobs – All queries for a Contact segmentation job must contain the Contact business object as a source.

What is segmentation and why is it important?

Segmentation helps marketers to be more efficient in terms of time, money and other resources. Market segmentation allows companies to learn about their customers. They gain a better understanding of customer’s needs and wants and therefore can tailor campaigns to customer segments most likely to purchase products.

What is segment used for?

Segment is a Customer Data Platform (CDP), which means that we provide a service that simplifies collecting and using data from the users of your digital properties (websites, apps, etc). With Segment, you can collect, transform, send, and archive your first-party customer data.

Why is segmentation needed?

What are the functions of segments in computer graphics?

Each segment corresponds to a component and is associated with a set of attributes and image transformation parameters like scaling, rotation. Presence of Segment allows : Subdivision of picture. Visualization of particular part of picture. Scaling, rotation and translation of picture.

What is the purpose of image segmentation in Photoshop?

The goal of segmentation is to simplify and/or change the representation of an image into something that is more meaningful and easier to analyze. Image segmentation is typically used to locate objects and boundaries (lines, curves, etc.) in images.

Which is the result of image segmentation in edge detection?

Image segmentation. The result of image segmentation is a set of segments that collectively cover the entire image, or a set of contours extracted from the image (see edge detection ). Each of the pixels in a region are similar with respect to some characteristic or computed property, such as color, intensity, or texture.

Why do you rename segments in computer graphics?

Renaming a Segment : This is done to achieve Double Buffering i.e. the idea of storing two images, one to show and other to create, alter and for animation. If both old and new segment names are not valid, give error message : “Segment names are not valid names” and go to step 6.
