i encountered problem in app. i have have uinavigationbar in pages, , created uinavigationcontroller 'embed in' first page. uinavigationbar appears on it, when perform segue first page (by instating new view controller , presenting it) navigation bar doesn't appear on second view controller. check segue presenting or pushing second page. check out segue properties, if it's presenting selection of 'modal' on segue property of attribute inspector. on presenting view controller won't navigation bar. navigation bar when push segue. and if want presenting animation on push using segue, can go custom segue. here link. http://www.appcoda.com/custom-segue-animations/

tl;dr: how measure area enclosed contour rather contour line itself i want find outline of object in below image , have code works cases. thresholding , adpative thresholding not work reliably ligthing changes. use canny edge detection , check area ensure found proper contour. however, once in while, when there gap cannot closed morphological closing, shape correct area of contour line instead of whole object. what use convexhull , returns contour around object. however, in case object curves inwards along top , convexhull isn't approximation area anymore. i tried using approxpolydp area gets returned of contour line rather object. how can approxpolydp return similar closed contour around object, convexhull function does? code illustrating using above picture: import cv2 img = cv2.imread('img_0.jpg',0) cv2.imshow('original', img) edges = cv2.canny(img,50,150) cv2.imshow('canny', edges) contours, hierarchy = cv2.findcontours(edges,...

how can minimum , maximum exponent 32- , 64-bit real numbers? doing work avoid underflows , overflows , need know numbers. i need base floating point numbers. is possible in fortran equivalent of ilmach ? for non-zero reals, numeric model looks s*b^e*\sum_{k=1}^{p}f_k*b^{-k} . to value of base b use radix() . minimum , maximum values of exponent e can found exponent combined tiny , huge . use, intrinsic :: iso_fortran_env, : real32, real64 print 1, "real32", radix(1._real32), exponent(tiny(1._real32)), exponent(huge(1._real32)) print 1, "real64", radix(1._real64), exponent(tiny(1._real64)), exponent(huge(1._real64)) 1 format (a," has radix ", i0, " exponent range ", i0, " ", i0, ".") end
