You look at a region of the image. If all the pixels are roughly the same color (below some threshold), you store the average color for the whole region as a single value. If the pixels vary too much, you split the region into four quadrants and try again.
Suppose you're building a map application. You have millions of restaurants, gas stations, and landmarks, each with a latitude and longitude. A user taps the screen and asks: "What's near me?"

63-летняя Деми Мур вышла в свет с неожиданной стрижкой17:54
Following the press screening at the New York Film Festival, Jarmusch said in a Q&A that he didn't make this movie with a message in mind. To suggest there's a resolute message would be to misrepresent the gentle development of every section of this film. Yet viewed as a whole, I found FATHER MOTHER SISTER BROTHER breathtaking in what it has to say about family. On one level, it's a reminder that every family is different and the same. We are all connected by a bunch of experiences, big and small, that are just so common they might be overlooked without the focus of a filmmaker on them. But beyond that, FATHER MOTHER SISTER BROTHER is a cool, rich, and wonderful celebration of familial love, which binds us and defines us — but not entirely.

Compared to the third-gen Polaroid Now Plus, my former retro pick, the Flip delivers clearer shots with fewer wasted photos, making the extra $50 worthwhile given that eight I-Type sheets are a spendy $18.99. The increased clarity can be attributed to several factors, including the Flip’s sonar autofocus and a four-lens hyperfocal system — which result in sharper, more focused images — along with its excellent flash. It’s the most powerful of any Polaroid camera, and while it can sometimes overexpose images, you can adjust exposure directly from the camera or app. The Scene Analysis feature also helps by warning if a shot is likely to be over- or underexposed, or if you’re too close to your subject. In my experience, the warnings didn’t always prevent overexposure, but they did leave me with shots that looked less blown than those from the Now Plus.
