The difference between expert classification and image segmentation?
image segmentation refers to clustering or grouping of homogeneous pixels into various groups while classification is next hierarchy which labell those clustered pixels as different classes..
●Active Stereo Vision ●Two or more cameras placed at different locations ●One is usually stationery other can be moving ●Passive Stereo Vision
●Two cameras separated by a distance known as base length in the same plane
Why do you need image segmentation?
Image segmentation is essential for isolating and analyzing specific regions within an image, enabling more accurate interpretation and understanding of visual data. It helps in various applications, such as object detection, medical imaging, and autonomous vehicles, by allowing systems to differentiate between objects and their backgrounds. By segmenting images, algorithms can perform tasks more efficiently, improving performance in areas like classification and recognition. Overall, it enhances the effectiveness of computer vision systems.
What does stylised image mean?
A stylised image refers to a representation that emphasizes certain features or characteristics while simplifying or exaggerating others, often to create a specific artistic effect or convey a particular mood. This approach is commonly found in illustrations, animations, and graphic designs, where the artist intentionally departs from realistic depiction to enhance visual impact or express a concept. Stylisation can involve alterations in color, form, and detail, allowing for creative interpretation and expression.
as a general rule of thumb, about 5 times the highest frequency for quality reproduction, although one can sometimes get away with a minimum of 2 times.

Where can you download Simulink?
Simulink is a package that is available along with Matlab. But these two are licensed. These can not be downloaded for free.
One can purchase the package.
What is the Matlab code to find percentile?
In MATLAB, you can use the prctile function to find percentiles of a dataset. For example, to find the 25th and 75th percentiles of an array data, you would use the following code:
percentiles = prctile(data, [25, 75]);
This will return an array containing the specified percentiles. Make sure that the data variable is a vector or matrix containing the values from which you want to calculate the percentiles.
prewitt filter is kind of edge detection
and almost is better than many kind filter in edge detection
.............
the code in matlab is:
i=imread('cameraman.tif');
edge_p=edge(i,'prewitt');
