Guyzz all those who have any doubt regarding whether the concepts in this video are right or no they can watch the following video for complete understanding . ruclips.net/video/UySm942McV0/видео.html
In errorsion we consider bohut the seed element and 4 neighbouring element must match then we give it one but in case of inverse A and B2 there is a problem in 2nd row 1 st element in errosion matrix it should be 0 as the seed element do not match.
What is the smallest number of different structuring elements that you would need to use to locate all foreground points in an image which have at least one foreground neighbor, using the hit-and-miss transform? What do the structuring elements look like?
Yes you are right that is because there were two structuring elements B1 and B2 given in the question. Only when one structuring element say B1 is given then we can assume B2 to be the compliment of B1
Sorry I could not understand your question properly Normally for a 3 x 3 structuring element the center point is taken as the seed point. Are you asking what will happen if we take the element in 2nd column in the topmost row as the seed point?
@@ramanhari6464 if the seed element is one then whereever you have one in the stucturing element at all those places you should have one in the image then only the output will be 1. For more clarity you can look at this video ruclips.net/video/_P_EkWkSz_o/видео.html Here i have explianed dilation and erosion from the basic formula
For hit or miss just erosion is used however, I also have a video on dilation here. Dilation and Erosion concepts ruclips.net/video/_P_EkWkSz_o/видео.html Dilation shortcuts ruclips.net/video/KXVoZEnbs6E/видео.html Difficult to understand dilation sums ruclips.net/video/XUi26Fp-6bA/видео.html
See, hit and miss aims to match the structuring element, exactly to the image . Now if you see the structuring element b1, there is no match of b1 with the image right and hence you will get all zeros. Hope that helps.
Bhai wrong hai ye Agar tum bhi techmax use kr rahe ho to ye problem techmax mai galat solve kiya hai Erosion ke liye condition rehti hai ki sare elements match ho gaye to center element 1 se change hota vrna center element 0 hoga N hit miss mai erosion use hota hai or is numerical mai sbhi element 0 ho jayenge coz aisi konsi bhi condition nahi aa rahi jisme sabhi elements of structuring element match ho rahe ho
No bro, he has taught correctly....you may refer one of his videos in his playlist where he has given proof of its correctness....it will surely help! :)
Yes you can refer to my other videos of image morphology and then short cuts on dilation and erosion to verify from the basics how they are right . Or else you can also verify from matlab

Yep, thanks for your reply Pratik Jain. You are absolutely correct but this answer is not expected one. As described in homepages.inf.ed.ac.uk/rbf/HIPR2/thin.htm, I make use of (figure -1) 8 structural elements (2 structural elements rotated by 90,180,270) . I tested it on imaged given Japanese letter (like hindi 3) in article, i am not getting the result as given above article.
What should i do here? is that doing as yours for four times ... first time consider original image and compute hit and miss transform and compute hit and miss transform on consecutive results of.
Thanks for your video. You said b2 is complement of b1, but if thats the case, b2 = [1 1 1;1 0 1;1 0 1], which is complement of b1=[0 0 0;0 1 0;0 1 0] . But i can see your b2 is [0 1 0; 0 0 0; 0 0 0] which i dont agree.
james tanaka here b2 and b1 both were given in the question ... I said when say only one structuring element is given say b1 then take b2 as the complement of b1

Thanks for explaining 🎉

Only the 1s should match.
Thanks this helped a lot
Thank You very much Sir!!
Seriously made my day 👏👏👏👏 awesome explanation
What is the smallest number of different structuring elements that you would need to use to locate all foreground points in an image which have at least one foreground neighbor, using the hit-and-miss transform? What do the structuring elements look like?
Question -2 How can the hit-and-miss transform be used to perform erosion?
Question -3 How can the hit-and-miss transform, together with the NOT operation, be used to perform dilation?
in the given explanation b2 is not the compliment of b1 as first and last columns are same of b1 and b2
Yes you are right that is because there were two structuring elements B1 and B2 given in the question. Only when one structuring element say B1 is given then we can assume B2 to be the compliment of B1
@@pratikian okay sir understood thanks
Sir, when u too compleent of, u forgot to make the second last row full 1..😁
Please understand I took A complement and not (A erosion b1) complement
@@pratikian got it sir..opps😁..Thank you so much for correcting me❤
@@Pishkoo 😇 all the best !
in a erosion b1 if seed point is in topmost row second coloumn then it should be one right??
Sorry I could not understand your question properly
Normally for a 3 x 3 structuring element the center point is taken as the seed point.
Are you asking what will happen if we take the element in 2nd column in the topmost row as the seed point?
If seed element is one then is it rule that one should be checked only placing it above 1 in the mani matirix

Here i have explianed dilation and erosion from the basic formula
Thanks brother.I will understand Ur concept.....
I think in erosion complete structuring element shud be match...Correct me plz
Please see my video on erosion for complete understanding
No any of 1s are enough
Sir through this topic erosion only happen or Dilation also happens ahh sir
For hit or miss just erosion is used however, I also have a video on dilation here.

taking b2 as the complement of b1 (if b2 is not given ),then we get final answer as all zero's which is wrong i feel!!!
See, hit and miss aims to match the structuring element, exactly to the image . Now if you see the structuring element b1, there is no match of b1 with the image right and hence you will get all zeros. Hope that helps.
Bhai wrong hai ye
Agar tum bhi techmax use kr rahe ho to ye problem techmax mai galat solve kiya hai
Erosion ke liye condition rehti hai ki sare elements match ho gaye to center element 1 se change hota vrna center element 0 hoga
N hit miss mai erosion use hota hai or is numerical mai sbhi element 0 ho jayenge coz aisi konsi bhi condition nahi aa rahi jisme sabhi elements of structuring element match ho rahe ho

It's actually wrong

Tq sir....

Thank u dost aaj pass ho jaungaaa😀😀
Most welcome .😊👍
I guess they never miss, huh
+SOUND LION the zeros in the final ans represents miss and 1s represent hit

What if three structuring element are given
have you seen a sum with 3 struvturing elements ?
its wrong.. this is not erosion..

Thanks for your video. You said b2 is complement of b1, but if thats the case,
b2 = [1 1 1;1 0 1;1 0 1],
which is complement of b1=[0 0 0;0 1 0;0 1 0] .
But i can see your b2 is [0 1 0; 0 0 0; 0 0 0] which i dont agree.
james tanaka here b2 and b1 both were given in the question ...
I said when say only one structuring element is given say b1 then take b2 as the complement of b1
