- Abstract: In this paper, we investigate the applicability of the CLIP-EBC framework, originally designed for crowd counting, to car object counting using the CARPK dataset. Experimental results show that our model achieves second-best performance compared to existing methods. In addition, we propose a K-means weighted clustering method to estimate object positions based on predicted density maps, indicating the framework's potential extension to localization tasks.

We argue that the empirical attainment function (EAF) has several advantages over the target-based ECDF.
The EAF does not require defining a priori quality targets per function, captures performance differences more precisely, and enables the use of additional summary statistics.
To facilitate the accessibility of the EAF, we integrate a module to compute it into the IOHanalyzer platform.

We propose a Collaborative video object segmentation by Foreground-Background Integration (CFBI) approach.
CFBI separates the feature embedding into the foreground object region and its corresponding background region, implicitly promoting them to be more contrastive and improving the segmentation results accordingly.
Based on CFBI, we introduce a multi-scale matching structure and propose an Atrous Matching strategy, resulting in a more robust and efficient framework, CFBI+.
