i using opencv 2 images manipulations in ycbcr color space. moment can detect noise due conversion rgb -> ycbcr , ycbcr -> rgb, said in documentation : if use cvtcolor 8-bit images, conversion have information lost. many applications, not noticeable recommended use 32-bit images in applications need full range of colors or convert image before operation , convert back. so convert image in 16 or 32 bits, didn't found how numpy. ideas? img = cv2.imread(imgnamein) # here want convert img in 32 bits cv2.cvtcolor(img, cv2.color_bgr2ycr_cb, img) # image processing ... cv2.cvtcolor(img, cv2.color_ycr_cb2bgr, img) cv2.imwrite(imgnameout, img, [cv2.cv.cv_imwrite_png_compression, 0]) thanks @moarningsun, problem resolved: i = cv2.imread(imgnamein, cv2.cv_load_image_color) # need sure have 8-bit input img = np.array(i, dtype=np.uint16) # line change type, not values img *= 256 # values in 16 bit format

i developing cocoa app need create menu , submenu's in application. i have attached screenshot designed using flex. how can same in cocoa. any appreciated. thanks. your question incomplete,though try match solution expecting…the screenshot posted(you never mentioned source of screenshot have taken,by analysing design edited in question “flex”) looks don’t want deal nsmenuitem , nsmenu classes drop down menus… solution 1 : make custom view(probably subview of nsview popview ) handles input, displaying labels,imageviews etc. ==> basically,both menu bar , menu item wrapped nsview , drop down menu wrapped nspanel…well per design have use nsview,because able add corner , yes,there possibility of adding ground colour well…the menu item has subviews of nstextview. if menu bar item has 1 text subview title, , if sub menu item has 3 text subviews, 1 check mark, 1 title , 1 hot key list…no need worry handling events,the respective classes own event handling…it’s

i trying create 'panoramacontrol' control windows phone 8, in terms displays slideshow of scenes, each of them having size of screenwidth. have tried using microsoft's panorama control have abandoned approach several reasons: the amount of scenes around 10-20, , might panoramacontrol handle, because there animation inside. i don't want control loop continuously, , panoramacontrol does. after research decided implement control on own, using scrollviewer , listbox , , result here: https://www.youtube.com/watch?v=2rcqdmkn0ey (the movement smooth on both device , emulator, bit choppy in link due screen capture) what missing however, scene scene snap-to-edge elastic functionality. have tried playing manipulation events, fail smooth elastic inertial movement , thought of asking suggestion towards elegant implementation before getting frustration or worse.. hacking , compromising.. therefore or suggestions (even towards different approaches) appreciated! :)

this question has answer here: possibility of duplicate mongo objectid's being generated in 2 different collections? 4 answers ok, have members collection , pet members collection, understand basic workings on how ids generated, there chance id gets assigned pets collection same members collection? the reason ask, improving social networking site, uses mongodb @ core. while social site give each pet id ( case if owner buys id ) use "_id" or '$id' main id in our database. so question possible knowing 2 totally separate collections end same id each other? - don't want. mongodb's objectid unlikely collide. contains counter, random number, process id, etc. objectids generated on different servers have different random number, process id, etc. objectids generated on same server differ in counter part.

i have base class define couple of empty methods. enforce/make mandatory definition of these methods in subclass , make crash @ init in case not overriden. ex: class shape: def __init__(self, name): self.name = name def number_of_edges(self): pass # method has overloaded in subclass class triangle(shape): def __init__(self, name): super(triangle, self).__init__() def number_of_edges(self): return 3 it seems python way raise notimplementederror : def number_of_edges(self): raise(notimplementederror) but beneficial crash , detect lack of implementation during class instantiation. why not default, , can done? use abc module create abstract base class. import abc class shape(object): __metaclass__ = abc.abcmeta def __init__(self, name): self.name = name @abc.abstractmethod def number_of_edges(self): pass any method decorated @abc.abstractmethod decorator trigger typeerr

this class structure: class mymixin(object): def __init__(self, **kwargs): super(mymixin, self).__init__(**kwargs) class mybaseview(mymixin, templateview): def __init__(self, **kwargs): print 'mybaseview init' super(mybaseview, self).__init__(**kwargs) class mycommonview(mybaseview): def __init__(self, **kwargs): print 'mycommonview init' super(mycommonview, self).__init__(**kwargs) class myview(mycommonview): def __init__(self, **kwargs): print 'myview init' super(myview, self).__init__(**kwargs) in urls.py: url(r'^some/url/$', myview.as_view()) also, there instance variables defined in each constructor. didn't write them here because don't think relevant. result... myview , mycommonview init messages printed, mybaseview doesn't. so, mybaseview's constructor never gets called. know fact constructor isn't called because see things not initialized
