Measure on Photo Image Measurement Tool

What it does

Measure on Photo is a free online image measurement tool. Upload a picture, set one known reference size, and measure any object in the photo — no signup.

The free online image measurement tool — measure any object in a photo from one known reference size. Upload a picture, mark one dimension you know, and read off the real-world size of everything else in the frame — distances, areas, and angles, with perspective correction built in. You measure an object in a photo using a reference size: one known dimension in the frame unlocks every other dimension. Four steps, under a minute. Drag, click, or paste a JPG, PNG, WEBP, or PDF. The image auto-fits to the canvas with pinch-zoom and pan. Draw a line along something with a known length and type in its real dimension. That single reference calibrates the whole image. Click any two points — or…from measureonphoto.online

  Clipto MCP▲655

  Hey HN, We recently built Clipto. It’s a tool that lets you search over terabytes of video, audio, and images on your computer, without relying on the cloud. Motivation: we probably all had this similar experience, we know a moment exists in a video or audio, but finding it takes hours scrubbing the timeline. You can send all the media to process in the cloud, but it’s slow, expensive and raises privacy concerns. So we decided to build our own on-device media search engine. How it works (high level): 1. We ingest video, audio, image; normalize formats via ffmpeg; run content analysis to…

  Simple algorithm and color space to generate diverse skin tones▲627

  Hello HN! I found that picking out plausible but diverse skin tones for my digital art and game development projects was kind of difficult, and I got curious about if there was a way to define a color space that made it easy. I've built a color picker and procedural generation algorithm based on the space as well as a bunch of other fun js features and demos throughout the page that use the equations. If you find it interesting, I have lots of explanations of how I built it and what properties the space has. The methodology might be a bit shaky, but hopefully the result is as helpful for…
