Okay, let’s go through one by one: I’m looking to extract pitches from a sound signal. Although I am not an expert and have had minimal formal training, I think I know the best answer to this problem. I’ve done a lot of searching, reading, and experimenting over the past few years. My consensus is … Read more
As e.g. shown in this Matlab Central page, the sharpness can be estimated by the average gradient magnitude. I used this in Python as from PIL import Image import numpy as np im = Image.open(filename).convert(‘L’) # to grayscale array = np.asarray(im, dtype=np.int32) gy, gx = np.gradient(array) gnorm = np.sqrt(gx**2 + gy**2) sharpness = np.average(gnorm) A … Read more
Programmatically, you mean? You can get it from Package#getImplementationVersion(). String version = FacesContext.class.getPackage().getImplementationVersion(); There are by the way also getImplementationVendor() and getImplementationTitle() methods. You might want to use it as well in order to distinguish the vendor (MyFaces or Mojarra, for example). Or do you mean manually? Just look in /META-INF/MANIFEST.MF file of the JSF … Read more
Enjoy, I was the original author of this. extern “C” { const char *getBuild() { //Get current architecture, detectx nearly every architecture. Coded by Freak #if defined(__x86_64__) || defined(_M_X64) return “x86_64”; #elif defined(i386) || defined(__i386__) || defined(__i386) || defined(_M_IX86) return “x86_32”; #elif defined(__ARM_ARCH_2__) return “ARM2”; #elif defined(__ARM_ARCH_3__) || defined(__ARM_ARCH_3M__) return “ARM3”; #elif defined(__ARM_ARCH_4T__) || defined(__TARGET_ARM_4T) … Read more
Tensorflow has just released an official Object Detection API here, that can be used for instance with their various slim models. This API contains implementation of various Pipelines for Object Detection, including popular Faster RCNN, with their pre-trained models as well.
You can use the os gem: gem install os And then require ‘os’ OS.linux? #=> true or false OS.windows? #=> true or false OS.java? #=> true or false OS.bsd? #=> true or false OS.mac? #=> true or false # and so on. See: https://github.com/rdp/os
It seems to be a layout bug. Drag one of the column headers in the device chooser where the device should be and change the column width and it magically appears! You can also double click the device’s row even when it’s hidden, so you don’t have to resize the column each time.
If swfobject won’t suffice, or you need to create something a little more bespoke, try this: var hasFlash = false; try { hasFlash = Boolean(new ActiveXObject(‘ShockwaveFlash.ShockwaveFlash’)); } catch(exception) { hasFlash = (‘undefined’ != typeof navigator.mimeTypes[‘application/x-shockwave-flash’]); } It works with 7 and 8.
Quotes are from the above mentioned Zisserman paper – 4.2 Evaluation of Results (Page 11): First an “overlap criterion” is defined as an intersection-over-union greater than 0.5. (e.g. if a predicted box satisfies this criterion with respect to a ground-truth box, it is considered a detection). Then a matching is made between the GT boxes … Read more
