## TL;DR

This paper introduces an enhanced model for early lung cancer detection using CT scans and image processing techniques like Gabor filters and region of interest labeling.

## Contribution

The novel contribution is the development of the EIM-LTI model, which improves diagnostic accuracy compared to standard CNN approaches.

## Key findings

- The EIM-LTI model achieves 2.67% higher training accuracy and 2.7% higher validation accuracy than CNN.
- Cross-validation with 5 folds reaches 98.27% accuracy, and the model achieves 92% accuracy on unseen data.

## Abstract

In this work, the CT scans images of lung cancer patients are analysed to diagnose the disease at its early stage. The images are pre-processed using a series of steps such as the Gabor filter, contours to label the region of interest (ROI), increasing the sharpening and cropping of the image. Data augmentation is employed on the pre-processed images using two proposed architectures, namely (1) Convolutional Neural Network (CNN) and (2) Enhanced Integrated model for Lung Tumor Identification (EIM-LTI).•In this study, comparisons are made on non-pre-processed data, Haar and Gabor filters in CNN and the EIM-LTI models. The performance of the CNN and EIM-LTI models is evaluated through metrics such as precision, sensitivity, F1-score, specificity, training and validation accuracy.•The EIM-LTI model's training accuracy is 2.67 % higher than CNN, while its validation accuracy is 2.7 % higher. Additionally, the EIM-LTI model's validation loss is 0.0333 higher than CNN's.•In this study, a comparative analysis of model accuracies for lung cancer detection is performed. Cross-validation with 5 folds achieves an accuracy of 98.27 %, and the model was evaluated on unseen data and resulted in 92 % accuracy.
