i saw documentation of bwareaopen , confusing me number of pixels. when 8-neighbourhood , doesn't mean 9-pixels ? in function, specify number of pixels, , if see example provided in documentation, find mention 50-pixels , mean 10x5 window? so, if specify number of pixels, function do? mentions removing small pixels. mean? isn't each square in image matrix considered square? small pixel in case? thanks. you mixing 2 of variables. in documentation can see following: bw2 = bwareaopen(bw, p) bw2 = bwareaopen(bw, p, conn) where have p , conn variables. conn neighbourhood variable. chose values understand "neigbour". see example: conn=4; - x - x 0 x - x - conn=8 x x x x 0 x x x x higher numbers higher dimensions. p variable variable choose "small". the function bwareaopen delete white areas smaller p pixels. in example in documentation can see: bw = imread('text.png'); bw2 = bwareaopen(bw, 50); imshow...

basic idea of i'm doing. want grab users' likes , print them in cli application (python script listens get/post messages using twisted framework). i have done oauth via inline canvas html: <a target='_top' href="https://www.facebook.com/dialog/oauth/?client_id=1111111111111&redirect_uri=https://apps.facebook.com/xxxxxxx/&scope=user_likes">grant permissions</a> right seems well? okay i've gone real time subscriptions section within facebook app section , added see image* : http://i.stack.imgur.com/l2i3t.png , when run test, python code returns result, see*: http://i.stack.imgur.com/9d2ek.png so i'm stuck though. because expect happen when like callback show in callback script. i'm printing given render_post , render_get , responses come out fine, example get {'hub.verify_token': ['test'], 'hub.challenge': ['73678294'], 'hub.mode': ['subscribe']} {'hub.verify_...

there 2 entity classes , b, , instances a, b (a , b have same id). b subclass of ( b extends a). removed entity "b" database. then, saw "a" has not been deleted. s want. @ point of code, want remove "a" too. when entitymanager.remove(a) throws exception saying, detached entity can t removed. seems removing subclass entity makes superclass entity detached although superclass entity remains in database. can me remove instance a. note: , b have same ids because when create b, automatically created same id ( rule of inheritance). you should use session.delete(b) . deletes both records database. after having deleted b record native sql delete statement, have delete record accordingly native delete statement.

i started using c++ instead of delphi. , there things seem quite different. example don't know how initialize variables semaphores , criticalsections. know 2 possible ways: 1. initializing critical section in constructor stupid since every instance using own critical section without synchronizing anything, right? 2. using global var , initializing when form created seems not perfect solution, well. can tell me how achieve this? just short explanation need critical section : i'd fill listbox different threads. semaphore : different threads moving mouse, shouldn't interrupted. thanks! contrary delphi, c++ has no concept of unit initialization/finalization (but found out that). what left little. need distinguish 2 things: where declare variable (global, static class member, class member, local function, static in function -- guess covers all) where initialize variable (since concerned c api have call initialization function yourself) fact is, in case ...
