Background:

Cell localization is crucial in biological research but faces challenges with cell morphology variations and intensity heterogeneity.
Existing cell location maps lack scale information, leading to insufficient or inaccurate supervision for point and density maps.

Purpose of the Study:

To develop advanced methods for accurate cell localization by addressing morphological variability and scale information deficits.
To introduce a novel gradient-aware and shape-adaptive convolution and a pseudo-scale instance map for improved cell mapping.

Main Methods:

Developed Difference-Deformable Convolution (DDConv) to enhance robustness to color variations and adapt to diverse cell morphologies using gradient information.
Proposed the Pseudo-Scale Instance (PSI) map to provide adaptive scale information for each cell, enabling accurate supervision.

Main Results:

DDConv and PSI map significantly improve cell localization performance across three challenging tasks.
The proposed approach sets a new benchmark for cell localization accuracy compared to existing methods.

Conclusions:

The novel DDConv and PSI map effectively address key challenges in cell localization.
This work provides a significant advancement in automated cell analysis and mapping for biological applications.
