In this challenge, you need to find a specific pixel within an photograph (taken with a real camera).

You are passed an (R, G, B) tuple and an image, and you need to return a point (x,y) within the image that matches the RGB color given. The image may have multiple points that match the color; you only need to find 1.

The challenge is that you need to do it while reading as few pixels as possible. Your score will be total number of pixels read across all test cases.

If you wish, you can read the entire image into an array of RGB values, as long as you don't do any processing on the pixels. I allow this purely for efficiency purposes. For example, in Python, list(Image.open("image_name+".jpg").convert("RGB").getdata()) is ok.

Hardcoding locations is not allowed. Your algorithm should work well for more than just the test cases listed below. You are not allowed to save data between test cases. I've chosen RGB values that appear infrequently (<10) in the image (in case that makes a difference for your algorithm). If you are using randomness in your algorithm, please set a seed, so that your score is constant.

Images can be found on Github

    \$\begingroup\$ Is there any correlation in the images we will be tested on? (Can images be noise) If not, surely the only way will be randomly sampling until the correct pixel is chosen? \$\endgroup\$ – Blue May 24 '16 at 18:02

    \$\begingroup\$ @muddyfish the images are taken with real cameras of real objects, so there is optimization to be found. Your algorithm should definitely be targeting the images, just not the specific colors I give. \$\endgroup\$ – Nathan Merrill May 24 '16 at 18:04

Python, score: 14,035,624

First thing's first, here's the code:

from heapq import heappush, heappop
from PIL import Image
import random

random.seed(1)


def dist(x, y):
    return sum([(x[i] - y[i]) ** 2 for i in range(3)])


def gradient_descent(image_name, c):
    im = Image.open(image_name + '.jpg').convert('RGB')
    L = im.load()
    sx, sy = im.size
    heap = []
    visited = set()
    count = 0
    points = []
    for i in range(0, sx, sx / 98):
        for j in range(0, sy, sy / 98):
            points.append((i, j))
    for x in points:
        heappush(heap, [dist(c, L[x[0], x[1]]), [x[0], x[1]]])
        visited.add((x[0], x[1]))

    while heap:
        if count % 10 == 0:
            x = random.random()
            if x < 0.5:
                n = heap.pop(random.randint(10, 100))
            else:
                n = heappop(heap)
        else:
            n = heappop(heap)
        x, y = n[1]
        c_color = L[x, y]
        count += 1

        if c_color == c:
            p = float(len(visited)) / (sx * sy) * 100
            print('count: {}, percent: {}, position: {}'.format(len(visited), p, (x, y)))
            return len(visited)

        newpoints = []
        newpoints.append((x + 1, y))
        newpoints.append((x - 1, y))
        newpoints.append((x, y + 1))
        newpoints.append((x, y - 1))
        newpoints.append((x + 1, y + 1))
        newpoints.append((x + 1, y - 1))
        newpoints.append((x - 1, y + 1))
        newpoints.append((x - 1, y - 1))

        for p in newpoints:
            if p not in visited:
                try:
                    d = dist(c, L[p[0], p[1]])
                    heappush(heap, [d, [p[0], p[1]]])
                    visited.add(p)
                except IndexError:
                    pass

and here's a gif showing how the algorithm examines pixels:

So, here's what this code is doing: The variable heap is a priority queue of (x, y) coordinates in the image, sorted by the Euclidean distance of the color at that coordinate to the target color. It gets initialized with 10,200 points which are evenly distributed across the entire image.

With the heap initialized, we then pop off the point with the minimum distance to the target color. If the color at that point has a distance > 0, that is to say, if the color at that point is NOT the target color, we add the 8 surrounding points from it to heap. To ensure that a given point isn't considered more than once, we maintain the variable visited, which is a set of all the points that have been examined so far.

Occasionally, instead of directly taking the point with the minimum color distance, we'll randomly choose some other point from near the top of the queue. This isn't strictly necessary, but in my testing, it shaves off approximately 1,000,000 pixels from the total score. Once the target color is found, we simply return the length of the visited set.

Like @Karl Napf, I ignored the test cases where the specified color was not present in the image. You can find a driver program to run through all the test cases at the GitHub repository I created for this answer.

Here are the results from each specific test case:

    \$\begingroup\$ That nearest neighbour search with multiple seeds is great! I also considered using a BFS over a DFS with a heap just like you, but the quadsearch is too broad. \$\endgroup\$ – Karl Napf Jun 26 '16 at 21:09

  • While there are no PNGs to parse and there are still problems with the testcases, I decided to program anyway.
  • Those testcases where the value is not present in the image were ignored (checked against a traditional linear search, which had a score of 544,017,431)

It is a recursive quad-section search. Sometimes it finds the correct value in a few percent, sometimes over 75%. Here are the results for all testcases:
