RectLabel Overview

What is RectLabel? RectLabel is an offline image annotation tool that allows users to draw polygons, cubic bezier curves, line segments, and points for object detection and segmentation. It also enables users to draw oriented bounding boxes in aerial images, draw keypoints with a skeleton, and draw pixels with brushes and superpixels. The app supports various formats for reading and writing, including PASCAL VOC xml and YOLO text formats, and allows for exporting to CreateML object detection and image classification formats, COCO, Labelme, YOLO, DOTA, and CSV formats, indexed color mask image, and grayscale mask images. The app also offers settings for objects, attributes, hotkeys, and labeling fast, and allows for customizing the label dialog to combine with attributes. Additionally, the app provides automatic labeling using CoreML models and automatic text recognition using OCR. Users can also use the app to convert video to image frames and augment images.

Software Reviews and Criticism

  • By Hazeo

    Developer is deceptive and greedy

    I echo other reviewers’ anger on the developer’s deception and greed, and cannot recommend this despite it being a simple but useful program. We are forced to pay a 'new full price’ on an app we had purchased in order to continue using it. Us early adopters helped you by pushing the app up on the rankings, and making us pay more for using the same features is very poor practice. This is like buying a product on sale, then later asked to pay the full price. With my own iOS app which I increased price over time I DID NOT ask existing users to pay more. Loss of revenue is completely acceptable in this case. If you want to charge for continued development, which is understanable, make new features as an in-app purchase without forcing existing users to pay more to use features they had access to before. This is very deceptive.

    Friendly Support

    There have been some negative reviews on the app because of the change in price model. I've been using the tool for a year and found it extremely helpful and reliable. Worth the money, even if they charged you 1$ at first. Not a big deal. I can also say that i've twice submitted issues on the github repo and the developers were quick to add features.

    Good product

    Works on laptop which is much faster and easier to use than a web based Developer was super helpful in adding new requested feature and general debugging. Everythin is 5 star. Documentation could be a little better but it is easy to figure out

    Features that I purchased were disabled

    I purchased this software, and then today when I go to add labels to my work, it wants to charge me $20 to enable the keyboard shortcuts I was using the day before! I'd buy it only because I don't want to waste a morning of productivity, but I get an error message! Looks like I need to spend the morning looking for an alternative. I can't recommend this software as the developer's inconsistency will cause you to loose productivity.
