  Nuclei segmentation and classification is the first and most crucial step
that is utilized for many different microscopy medical analysis applications.
However, it suffers from many issues such as the segmentation of small objects,
imbalance, and fine-grained differences between types of nuclei. In this paper,
multiple different contributions were done tackling these problems present.
Firstly, the recently released "ConvNeXt" was used as the encoder for HoVer-Net
model since it leverages the key components of transformers that make them
perform well. Secondly, to enhance the visual differences between nuclei, a
multi-channel color space-based approach is used to aid the model in extracting
distinguishing features. Thirdly, Unified Focal loss (UFL) was used to tackle
the background-foreground imbalance. Finally, Sharpness-Aware Minimization
(SAM) was used to ensure generalizability of the model. Overall, we were able
to outperform the current state-of-the-art (SOTA), HoVer-Net, on the
preliminary test set of the CoNiC Challenge 2022 by 12.489% mPQ+.
