Accurate visual localization exploiting street-level imagery

Jonas Meyer
FHNW
Talk 30 Minutes
Tuesday, June 21: 11:15 - 11:45

Visual localization is a key technology for applications such as augmented, mixed and virtual reality, as well as robotics and autonomous driving. It addresses the problem of estimating the 6-degree-of-freedom (DoF) camera pose from which a given image or sequence of images was captured relative to a reference scene representation, often in the form of images with known poses. Although much research has been done in this area in recent years, large variations in appearance caused by season, weather, illumination, and man-made changes, as well as large-scale environments, are still challenging for visual localization solutions. To overcome the limitations caused by appearance changes, traditional hand-crafted local image feature descriptors such as SIFT (Lowe, 2004) or SURF (Bay et al., 2008) are replaced by learned feature descriptors such as SuperPoint (DeTone et al., 2018), R2D2 (Revaud et al., 2019), ASLFeat (Luo et al., 2020), DISK (Tyszkiewicz et al., 2020) or ALIKE (Zhao et al., 2022). Hierarchical approaches combining image retrieval and structure-based localization (Sarlin et al., 2019) are developed to deal with large environments, both to keep the required computational resources low and to ensure the uniqueness of the local features.

Formulating geospatial data questions to answer big problems

bonny mcclain
data & donuts
Talk 45 Minutes
Tuesday, June 21: 16:30 - 17:15

Data storytelling has never been more popular. Immanuel Kant stated the following in 1802, "The history of occurrences at different times, which is true history, is nothing other than a consecutive geography, and thus it is a great limitation on history if one does not know where something happened, or what it was like”.

To truly bring history to light we need to bring the right data into the conversation, use the right tools, and be able to hold a tension between what we would like the solutions to be and what limits the actual realization of change. The story I would like to tell by engaging spatial and non-spatial data centering around the role disinformation and politics played in the profound deforestation of the Amazon since 2018. What can we measure? What should we be measuring?

Robyn: An async web framework written in Rust

Sanskar
Bloomberg LP
Talk 30 Minutes
Tuesday, June 21: 16:00 - 16:30

Python web frameworks, like FastAPI, Flask, Quartz, Tornado, and Twisted, are important for writing high-performance web applications and for their contributions to the web ecosystem. However, even they posit some bottlenecks either due to their synchronous nature or due to the usage of python runtime. Most of them don’t have the ability to speed themselves due to their dependence on *SGIs. This is where Robyn comes in. Robyn tries to achieve near-native Rust throughput along with the benefit of writing code in Python. In this talk, we will learn more about Robyn. From what is Robyn to the development in Robyn.
