          Figure 1. An example from DeepPatent2 extraction results for US Design Patent #0836880 (Figure 1 in DeepPatent2 ) Introduction Technical illustrations and drawings, unlike natural images, are designed for straightforward human comprehension, focusing on details such as strokes, lines, and shading rather than colors and gradients ( Carney and Levin, 2002 ) [2]. While computer vision has extensively studied natural images for object recognition and understanding context, technical drawings, prevalent in design patents, remain less explored. These drawings do not contain rich information such as color and gradient as appearing in natural images, making them distinct from typical natural images ( DeepPatent ) [6]. Recent developments in sketch-based datasets like QuickDraw [3], TU-Berlin [4], and ImageNet-Sketch [5] have provided valuable resources for sketch-based image retrieval. In this blog, we summarize our paper titled, " DeepPatent...

  Figure 1: TimeMap for the URL https://twitter.com/elonmusk/status/1675187969420828672 On July 1, 2023, Elon Musk posted a tweet that was archived multiple times by the Wayback Machine. Figure 1 shows a representation of the TimeMap for the URI-R (URI of the original resource) of the tweet. Each timestamp shown indicates the time, or Memento-Datetime, when the URI-R was archived. In this interface, the color of the timestamp indicates the type of HTTP response that was received at the time of archiving. A blue timestamp indicates an archived HTTP 200 response (the URI-R returned the expected result), a green timestamp indicates an archived HTTP 302 response (the URI-R redirected), and an orange timestamp indicates an archived HTTP 404 response (the URI-R was not found). Each timestamp links to a URI-M , which is the URI of the archived webpage, or memento. Typically, we can take the first appearance of a URI-M in a TimeMap as evidence that the URI-R existed at that Memento-D...
