boundary

I've a binary image containing an object as illustrated in the figure below. The centerline of the object is depicted in red . For each pixel belonging to the object, I would like to relabel it with a color. For instance, pixels whose orthogonal distance to the centerline are half of the distance to the object boundary from the centerline, should be labeled blue , otherwise green . An illustration is given below. Any ideas? Also, how could I fit a 1D gaussian centered in the object centerline and orthogonal to it? The image in full resolution can be found under: http://imgur.com/AUK9Hs9 Here

Huge plain-text data file I read a huge file in chunks using python. Then I apply a regex on that chunk. Based on an identifier tag, I want to extract the corresponding value. Due to the chunk size, data is missing at the chunk boundaries. Requirements: The file must be read in chunks. The chunk sizes must be smaller than or equal to 1 GiB. Python code example identifier_pattern = re.compile(r'Identifier: (.*?)\n') with open('huge_file', 'r') as f: data_chunk = f.read(1024*1024*1024) m = re.findall(identifier_pattern, data_chunk) Chunk data examples Good: number of tags equivalent to number of

I have two images(small and big). Big one contains a small one. Like if the small one is a photo and a big one is a page from the photo album. How do I get coordinates of that small image in the big one using PHP? And also I need to know the size of that image in big one...so just a(x,y) coordinate of any angle and sizes of sides of that presentation of the small image... (x,y, width, height) I've already asked the question like that and got a brilliant answer ( here ) but I've forgot to mention over there that the size of a small image could be different from the the size of that image in the
