#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 (https://groups.google.com/g/tesseract-ocr/c/Wdh_JJwnw94/m/24JHDYQbBQAJ). 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 https://groups.google.com/g/tesseract-ocr/c/Wdh_JJwnw94/m/24JHDYQbBQAJ
    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
