From the archive! Generating Histogram Colour Analysis Graphs From Images In PHP

In this article Phil looks at extracting the colour frequency from an image and generating a histogram based on the information found. He then looks at using colour ranges to segment the colour frequency into bins to create a simplified analysis.

Как сравниваются изображения — от MSE до Dino

Моя страсть к накопительству картинок зародилась еще в эпоху диалапа, когда каждый JPEG проявлялся построчно под писк и скрежет модема, а бэкап стянутых с BBS цифровых сокровищ на дискету напоминал ритуал. С тех пор куча скарба разрослась до масштабов домашнего дата‑центра: здесь доисторические смишные мемы, тонны диснеевского клипарта, сканы журналов, галереи фанарта от известных в узких кругах артоделов, масса неотсортированного фототреша из собственных поездок, картинки природы и красоток, порция клубнички, шедевры CGI, нейроарт и фотографии Элизабет Уинстон. Проблема в том, что весь этот терабайтный зоопарк из разных разрешений, битности и форматов — абсолютно неструктурированная свалка, и попытка найти нужное превращается в квест «убей свои выходные». По мере роста коллекции я пробовал подряд все костыли, которые лучшие умы изобретали для сравнения изображений. В этой статье я пройдусь по эволюционной цепочке: от одноклеточных хэш‑сумм до венца творения — свежесобранного монстра DINOv3. Объять необъятное не выйдет — по каждому методу сравнения можно катать лонгрид иллюстрациями и с примерами кода (что, возможно, и сделаю, если меня не закидают жжёными тряпками). Но сейчас попробую изложить суть: как метод устроен, когда он тащит, а когда выдает откровенный бред. Поехали

How many covers before an album is a "cover album"? Here is a #histogram of the % of songs on albums that are covers.

Do you consider cover albums as part of a band's primary releases? A short discussion on this and more:

TIL about Enumerable#tally and of course this exists. Little surprised it's not #histogram but ok

Alright alright, one more.

Here's a #histogram of themes per heavy #metal band.

Looks like average is just shy of 3 themes per band (with themes) with some having as many as 10 themes.

For part 2 of the Understanding Latency Series, we are doing a bit of mixing and matching.

Perhaps you have heard of "Tail At Scale", the CACM article that periodically made the rounds in the last decade. In this post, we provided interactive charts so you can play with that kind of setup and *see* for yourself the profound effect of simply issuing multiple requests at once.

If a better understanding of service runtime and learning to improve software performance is part your 2024 resolution (or not), may I suggest you start with a series of articles I am writing under the theme, Understanding Latency Series?

The first post, Latency Is A Curve, answers an existential question—how do you approach latency, after all?

I know this doesn't make me a "grown up researcher," but I always get a giggle when a histogram or bar chart gives me the finger.
