-
Image
I want to use graph cut algorithm on images in my project, I use Python 2.7 I found, but the documentation does not seem so obvious. I'm making an example, this is my 5 * 5 matrix: gt; & Gt; An array ([[0, 1, 2, 3, 4], [5, 6, 7, 8, 9], [10, 11, 12, 13, 14], [15, 16, 17, 18, 1] 9 virtual terminal node, S (source) and T , [20, 21, 22, 23, 24]] (sync) matrix The infinite weight for all pixels of the lowest columns on the left and right should be linked to the arcs. Here's what I want to get: This is my code to get it, but it does not work left_most = concatenate ((1, ashp [0]), N.P. Ranges (ashp [0]). Reshape (1, ashp [0])). Unstable (npuit 64 ) left_most = np.ravel_multi_index (Bayan_ most, Asp) right_most = concatenate ((np. that ((1, Asp [0])) size (A, 1) - 1, NP Krenj (Asp [0]). The new size to (1, Ashaip [0])). volatile (Np.uint64) right_most = np.ravel_multi_index (right_most, A.shape) g.add_grid_tedges (Bayan_ most, Anpikons (Bayan_ most. Shaip) *...

php - String Replace Date & Time -

-
A line of my XML looks like this: $ ob_time = $ xml- & gt; Observation_time_rfc 822; Echo $ ob_time; Output looks like this: Thursday, 09 October 2014 22:59:16 +0200 But what should I look like 2014-10-09 + 22 % 3A 59 % 3a 16 I think it can do the place of the string, someone can help me find me! Thanks! edit : use a ghost solution, it must be correctly Handles offset timezone First you need to reformat your date. You do this by parsing it with strtotime and formatting it with the date function. They are "URL instead of the funny% 3A" actually are URL-encoded characters: $ date = date ('y-m-d h: i: s', strotom ($ ob_time)); $ Date = urlencode ($ date); // 2014-10-09 + 20% 3A 59% 3A 16
