Leukemia is a life-threatening hematological malignancy characterized by the uncontrolled proliferation of abnormal white blood cells, where early and accurate diagnosis is crucial for effective treatment and improved patient survival. Traditional microscopic examination of blood smear images is labor-intensive, time-consuming, and highly dependent on expert interpretation, motivating the development of automated computer-aided diagnostic systems. This paper proposes a novel Quantum-Weighted Hybrid Feature Fusion Framework for automated leukemia cell classification using microscopic blood smear images. Initially, Contrast Limited Adaptive Histogram Equalization (CLAHE) is applied to enhance image quality and improve cellular visibility. Subsequently, a comprehensive set of handcrafted features, including quantum-inspired statistical descriptors, color moments, Gray-Level Co-occurrence Matrix (GLCM) features, Local Binary Pattern (LBP) features, wavelet coefficients, and morphological characteristics, are extracted to capture diverse cellular properties. In parallel, deep semantic representations are obtained using a pretrained ResNet50 network. A novel quantum-weighting mechanism based on entropy and purity measures is introduced to enhance the discriminative capability of deep features.
The weighted deep features and handcrafted descriptors are fused into a unified hybrid feature vector, which is further optimized using Principal Component Analysis (PCA) to reduce redundancy while preserving significant information. Finally, a Bagged Ensemble classifier is employed for robust leukemia classification under a five-fold cross-validation framework. Experimental evaluation on leukemia microscopic image datasets demonstrates that the proposed framework achieves an accuracy of 98.00%, sensitivity of 98.00%, specificity of 98.00%, precision of 98.00%, F1-score of 98.00%, and an AUC of 0.997, outperforming conventional machine learning and ensemble-based approaches. The results confirm that the integration of quantum-inspired weighting, hybrid feature fusion, and ensemble learning provides an effective and reliable solution for automated leukemia diagnosis.
