2021 Competition for Scene-Text-Detection-and-Recognition

The models Our model comprises two parts: scene text detection and scene text recognition. the descriptions of these two models are as follow: Scene Text Detection We employ YoloV5 [1] to detect the ROI (Region Of Interest) from an image and Resnet50 [2] to implement the ROI transformation algorithm. This algorithm transforms the coordinates detected by YoloV5 to the proper location, which fits the text well. YoloV5 can detect all ROIs that might be strings while ROI transformation can make […]

Pytorch based library to rank predicted bounding boxes using text/image user’s prompts

Pytorch based library to rank predicted bounding boxes using text/image user’s prompts. Usually, object detection models trains to detect common classes of objects such as “car”, “person”, “cup”, “bottle”. But sometimes we need to detect more complex classes such as “lady in the red dress”, “bottle of whiskey”, or “where is my red cup” instead of “person”, “bottle”, “cup” respectively. One way to solve this problem is to train more complex detectors that can detect more complex classes, but we […]

The NLP Cypher | 12.26.21

Merry Christmas 🎄 for those celebrating. And Happy New Year! Even OpenAI is feeling the holiday spirit: they open sourced their photorealistic GLIDE model several days ago. Includes three notebooks: The text2im notebook shows how to use GLIDE (filtered) with classifier-free guidance to produce images conditioned on text prompts. The inpaint notebook shows how to use GLIDE (filtered) to fill in a masked region of an image, conditioned on a text prompt. The clip_guided notebook shows how to use GLIDE […]

Optimal Scraping Technique: CSS Selector, XPath, & RegEx

Web scraping deals with HTML almost exclusively. In nearly all cases, what is required is a small sample from a very large file (e.g. pricing information from an ecommerce page). Therefore, an essential part of scraping is searching through an HTML document and finding the correct information. How that should be done is the matter of some debate, preferences, experience, and types of data. While all scraping and parsing methods are “correct”, some of them have benefits that may be […]
