In region growing algorithms, the seed point remains fixed throughout the process of growing the region. The seed point is typically chosen as the starting point for the region growing process, and it does not change as the region expands. Once the seed point is specified, the algorithm iteratively examines neighboring pixels and decides whether to include them in the region based on certain criteria (e.g., similarity to the seed point). However, the seed point itself remains unchanged, serving as a reference point for the region growing process. Changing the seed point during the region growing process could lead to inconsistent segmentation results and may not adhere to the intended segmentation criteria. Therefore, it's common practice to keep the seed point fixed throughout the region growing algorithm.
Came here to thank you di...today I have had my dip question paper and all the topics that you'd covered were there in the question paper...without yoh I can't even think how can I pass...now I've attempted all the questions correctly...thank you so much di...you're truely amazing ✨
@CollegeFriendly Hi! Nice video but I guess there is a key misconception here. The seed point should not change during region growing. This is because while handling 5, 4 will come into the region which means in the next step 2 and 1 will get absorbed followed by 0 and so on. Hence, the entire image will become a single segment. For a simpler understanding assume there are 256 points on a line with values 0,1,2,..., 255. Then 0 is similar to 1, 1 is similar to 2, 2 is similar to 3... 254 is similar to 255. If we keep changing the seed point, this will mean 0 and 255 will lie in the same segment even though they are separate both spatially and in intensity.
@@fahadmirza8497 actually there's mistake in the concept here...we are checking with the original point 7 all the time...as if you are taking adjacent pixels every time then whole image would come under 1 segment...so just check the value with 7 and so it would be 7-4 =3 so it cant be taken....
If I crack my Internal assessment with this help, I'll like the whole playlist's videos individually. I'll recommend to my friends as well since it has been helpful for me. Date: 10/04/2022 21:39
for those having confusion in ques 1 , the reason why 4 is not included is that we will check the difference from the initial element which is 7 so only elements included are 5,,6,5 satisfying the minimum threshold
In question 1 , for the element 5 in position (1,1) , while checking the absolute differences between its neighbours , isn’t the element 4 which is in position (2,1) will be in the region? I am having doubt in this part.
@@collegefriendly Okay thank you for clarifying. Your contents are very easy to understand as your topic has explanations as well as examples together.
@@collegefriendly Wouldn't then all the elements will get 'a' since difference between the two neighbouring pixels is ≤ 2. Perspective 2 - When 4 is compared with value 7. It'll be given a value 'b' that is 0 and will thus not participate further. Real solution - seed value doesn't change and will only be applied to 6.
3 is not an 8 way neighbour of any of the 6 valued Pixels. Since coordinates of seed point are not given, we will only grow the region based on neighbours of the seed value provided (6 here). Thus we do not include them in this example. However if the question was like Q1 where seed point coordinates were given, then we would have included 3 in our region.
I think solution is incorrect because here merging of region will depend on the order we select to compare the regions. So different users will get different values
hey mam you haven't included the geometric transformation in the series of digital image processing..rotation of image,translation of image,shearing of image etc..these are the most important topics you haven't covered
a real creator would have commented their mistake and pinned it! Bruh u can't just teach wrong stuff and let it pass even after knowing! f* now there's no point in even disliking the video, imma straight away report this video! Edit 1: bruh i was going through the comments and realized the question one wasn't wrong she didn't just explain. So ideally i should have deleted my comment but upon scrolling a little more she literally accepted the mistake and said she made a mistake and 4 needs to be included which surely doesn't have to be. But she accepted it as her mistake. This beacher doesn't even know what she's teaching! Edit 2: jaa nhi kar raa report aaj mood nhi h!
