balance

问题 I have 5 folders named as class_i each folder has the i class images. the images are with .jpg format. How can I balance the images in each folder by doing augmentation such that number of images in this folder will be equal to the number of images in the folder with highest number of images? Also, could you please help in plotting a curve shows number of images in each folder before and after balancing? 回答1: Just extended my other answer with algorithm that does exactly what you want in this

问题 I have this code to try around with halcon. Images are quite greenish, and cannot figure out how to set whitebalance. I cannot find it in the samples, in the documentation, on google, and in the parameters. How is whitebalance set on halcon? * Image Acquisition 06: Code generated by Image Acquisition 06 * Image Acquisition 06: Attention: The initialization may fail in case parameters need to * Image Acquisition 06: be set in a specific order (e.g., image resolution vs. offset). open

问题 Is that possible to avoid negative balance using MySql query? I have the following MySql table: trx_no trx_date Opening debit credit 1 2019-10-01 200 0 100 2 2019-10-02 200 0 100 3 2019-10-03 200 100 0 4 2019-10-03 200 400 0 5 2019-10-03 200 0 200 6 2019-10-04 200 0 100 7 2019-10-05 200 0 400 with this query: SELECT trx_no, trx_date, Opening, debit, credit, Opening + (SELECT SUM(t2.credit - t2.debit) FROM MyTable t2 WHERE t2.trx_no <= t1.trx_no) AS balance FROM MyTable t1 ORDER BY trx_no; I

问题 I want to calculate account balance using raw sql without extra application logic. Transaction schema includes amount, from_account_id and to_account_id My query is SELECT SUM(tdebit.amount) - SUM(tcredit.amount) as balance FROM accounts as a INNER JOIN transactions as tdebit ON a.id = tdebit.to_account_id INNER JOIN transactions as tcredit ON a.id = tcredit.from_account_id WHERE a.id = $1 AND tdebit.succeed = true AND tcredit.succeed = true And it does not work as I expected - result is

问题 I have 3 teams, They have 2 players, 3 players and 7 players. There is 18 players sitting on the sidelines waiting to be assigned. Each player has their own skill level, meaning a level 1 is not going to defeat a level 10. I want to balance the teams out to 10 players each. And I want to try get all 3 teams as equal in skill as I can. But I don't want to remove the players already in a team. But I'm not sure how I would accomplish this. I'm also not sure if there is a easy answer, or if this

问题 I'm trying to achieve a testing if a tree is AVL tree or not using prolog. I've made a height test that works for the tests I've done so far but my balancing test is still not going strong. This is my work so far: avl('Branch'(LeftBranch,RightBranch)) :- height(LeftBranch,H1), height(RightBranch,H2), abs(H1-H2) =< 1. I've based this code from an older stackoverflow code. But it doesn't work in all cases. Will include my height code. Somewhere I've made a misstake and Im sure where to find it.

问题 I am running a code to balance brackets in statement. I think i have gotten it correct but it is failing on one particular statement, i need to understand why? This is the test in particular it is failing "())(" More than the coding i think i need to fix the algo, any pointers? def balance(chars: List[Char]): Boolean = { def find(c: Char, l: List[Char], i: Int): Int={ if( l.isEmpty ) { if(c=='(') i+1 else if(c==')') i-1 else i } else if (c=='(') find(l.head, l.tail, i+1) else if(c==')') find
