Convert exported/downloaded Facebook friends file into a simple list of names or links (e.g. LinkedIn search URLs)
View convert-facebook-exported-friends.js
1. Download your contacts from Facebook's Settings area. When prompted to choose certain categories of data to export, you only need to select the "Friends" option.
2. You'll eventually be sent an email with a link to download your data.
3. Download the zip file and extract its contents. Within the `friends_and_followers` folder, open `friends.json`.
4. Copy the contents of that file into the line below marked, "Replace this line...".
5. In Chrome, type Cmd + Opt + J to open the Javascript Console or access View > Developer > Javascript Console.
6. Copy this entire file (with your data substituted at the appropriate line) into the Javascript Console and hit enter to execute the command.
7. The Console should generate a list of just the names of your friends which can be used however you like (e.g. for uploading to another service). There should be a small "Copy" button you can use to copy out the data.

An OpenCV utility function for displaying a set of easily-configurable trackbars and providing their results to an arbitrary callback - useful for quick prototyping and testing
#Usage: `python example.jpg`
import sys
import cv2
#### Example usage ####
def edge_detect(p):
edged = cv2.Canny(p["img"], p["low"] * 15, p["high"] * 15, apertureSize = (p["aperture"] * 2) + 3)
cv2.imshow("Edged", edged)

Optimally resize an image so that its line height is approximately 32 pixels (Keywords: OpenCV, Tesseract, OCR)
#Optimally resize `img` according to the bounding boxes specified in `boxes` (which is simply the (pruned) results from `pytesseract.image_to_data()`).
#Tesseract performs optimally when capital letters are ~32px tall ( Smaller text obviously can't be OCR'd as accurately, but weirdly enough, larger text causes problems as well. So, this function uses the bounding boxes we've found and resizes the image so that the median line height should be ~32px.
def optimal_resize(img, boxes):
median_height = np.median(boxes["height"])
target_height = 32 #See
scale_factor = target_height / median_height
print("Scale factor: " + str(scale_factor))
#If the image is already within `skip_percentage` percent of the target size, just return the original image (it's better to skip resizing if we can)
skip_percentage = 0.07
