What Is A Seed In Matlab

Region growing stops when a significant difference between the seed and the neighbour pixel is found.

What is a seed in matlab.

To create one or more independent streams separate from the global stream see randstream. Rng seed specifies the seed for the matlab random number generator for example rng 1 initializes the mersenne twister generator using a seed of 1. The algorithm for region growing scans seed image s x y to find a seed. Every time you use rand it gives you a random number that is what rand is for.

So i m not sure what the point of 2 is. Ensure that the behavior of code you write today returns the same results when you run that code in a future matlab release. Simple but effective example of region growing from a single seed point. The region is iteratively grown by comparing all unallocated neighbouring pixels t.

To create one or more independent streams separate from the global stream see randstream. Set the seed and generator type together when you want to. Simulink is the integrated environment of system modelling and simulation which is being widespread used this paper describes the matlab visual simulation of the propagation path loss model for. Setting seed in random normal.

When a seed is found the region growing is performed from this point over the originalimage jpg f x y. Seeding inside the loop means that all random numbers created inside the loop will be the same in each iteration. Ensure that the behavior of code you wrote in a. The rng function controls the global stream which determines how the rand randi randn and randperm functions produce a sequence of random numbers.

Seeding the random number generator means initializing it to a certain status. For example the following code sets the seed to 1 and the generator to mersenne twister. Rng seed specifies the seed for the matlab random number generator for example rng 1 initializes the mersenne twister generator using a seed of 1. But what if you want to repeat that random number for the purpose of duplicate your simulation results.
