In recent literature, significant strides have been made in the development of automated systems for detecting Leukemia from microscopic images. Researchers have successfully applied advanced technologies such as image processing, computer vision, and machine learning to create efficient and objective tools. These automated systems analyse cellular morphology, distinguishing normal and abnormal cells associated with Leukemia. The work not only enhances the speed and consistency of diagnosis but also allows for early detection and provides a scalable solution for processing large datasets. The continuous refinement of algorithms and integration into clinical practices holds promise for improving Leukemia diagnostics and ultimately contributing to better patient outcomes.
Kokeb et al.[7] introduced a methodology enhancing instance segmentation accuracy for nuclei detection through pre-processing steps and K-means clustering, aimed at identifying various types of Leukemia cells via an SVM algorithm. They employed metrics such as size, shape, and area for cancer cell segmentation[8]. By extracting features from images and utilizing classifiers built on SVM and GBDT, they demonstrated that a GBDT-based classifier significantly outperforms the SVM model, offering a versatile solution applicable across different platforms. Madhukar et al.[9] developed a decision support tool designed to assist in selecting the appropriate treatment intensity for childhood Acute Lymphoblastic Leukemia (ALL). The tool utilizes K-means clustering for segmenting data based on shape and texture features of the cells. This approach facilitates a more informed and precise decision-making process in determining the most effective treatment plans for young patients with ALL, highlighting the potential of machine learning techniques in enhancing patient care strategies. E.Fathi, et.al. [10] use of an adaptive neuro-fuzzy inference system (ANFIS) is well-suited for distinguishing between patient and non-patient individuals due to its ability to adapt and learn from data uncertainties. For more complex distinctions, such as between acute lymphoblastic Leukemia (ALL) and acute myeloid Leukemia (AML), feature reduction is essential to focus the classification process on key distinguishing attributes, improving both accuracy and model performance. S. S. Al-jaboriy et.al.[11] proposed an automatic leukocyte cell segmentation method utilizing machine learning and image processing techniques was developed, achieving a blast cell segmentation accuracy of 97The system uses 4-time feature analysis and artificial neural networks (ANN) to get the best results on blastema cells even under different lighting conditions. Francis E et.al.[12A computational method has been developed for the diagnosis of leukemia in microscopic blood. Perform histogram-based thresholding of the S component of the HSV color space and then perform morphological erosion for image segmentation. F. E. Al-Tahhan et.al.[13] presented quick and easy classification aims to distinguish all subtypes. Use a segmentation algorithm to capture the main features of the image dataset (10 geometric features). All possible variants of the extracted results are used to train and test some powerful classifiers such as KNN with different functions, SVM and ANN with different kernels. Mohapatra et.al.[14] implemented image segmentation and integrated classification systems are applied to blood microscopic images for early diagnosis of all subtypes. The extracted features are shape, contour, fractal, texture, color and Fourier descriptors. Although these methods give good results with 95% accuracy, they use different parameters, which requires a lot of time and effort. Dumyan, S. et.al.[15] using the developed method for cancer diagnosis using ANN classification, the classification accuracy is estimated to be 97.8%. Use features like patterns, texture properties, statistics and time constants. Karthikeyan, T.et.al.[16] suggested microscopic image segmentation using fuzzy C-means for Leukemia diagnosis. A classification is made by SVM after using Gabor texture extraction method, and the performance accuracy of this technique is of the rate 90%.In the realm of diagnosing and classifying acute lymphatic Leukemia (ALL) with machine learning, most approaches rely on extracting a large number of features to ensure accuracy, which often leads to overfitting and increased noise in the models. This complexity can extend the effort and time needed for the classification process. Nonetheless, a minority of studies have explored the use of algorithms that require fewer features, aiming for streamlined, efficient models that avoid overfitting while maintaining diagnostic precision. These approaches represent an important shift towards developing simpler, faster, and potentially more reliable diagnostic tools for Acute Leukemia[17]. Image segmentation is considered one of the most important steps in computer vision and image processing technology. In this method, the input image is split into multiple objects with the same set of objects to extract the region of interest (ROI) [18] Researchers have used various segmentation methods to detect cancer cells, such as region-based segmentation, growing region segmentation, edge detection segmentation, and cluster-based segmentation. [19][17]. Computer-assisted analysis of blood cells consists of several steps, including preparation, distribution of blood samples from smears, identification of blood cells, and distribution of blood cells. [20, 21]. Accurate detection of the region of interest (ROI), specifically blast cells, is crucial for the efficient classification of leukocyte cells. It's important to note that the majority of classification errors in white blood cells (WBCs) stem from inaccuracies in the segmentation phase. This highlights the critical role of precise segmentation in ensuring the reliability of automated blood cell analysis systems[22, 23, 24].The segmentation of leukocyte cells from microscopic images is challenging due to several factors: overlapping cells, variable image contrast, diversity in cell shapes and sizes, low contrast between objects and the background, and image noise. These difficulties are compounded in the case of white blood cells (WBCs) because of their intricate nuclear structure, making WBC segmentation particularly complex[25]. Researchers have used many different methods to identify tumors using microscopic blood, such as edge segmentation detection, clustering, thresholding, regional classification, and hybrid methods. More importantly, k-means clustering and edge-based segmentation are the most popular methods for cell segmentation in peripheral blood smears [26]. Li et al. [27] It has been shown that the combination of threshold and morphological function leads to a good segmentation result. Likewise, group segmentation presented by Fiehn et al. [28, 29, 30] are also widely used. Various embryonic cell segmentation techniques including otsu, histogram thresholding and flow markers have also been proposed [31, 32, 33]. Zhang et al. [34] presented HSI (Hue, Saturation and Intensity) color model uses k-means cluster segmentation technique to transform cell images into other models. Ko et al. [35] Segmentation of WBC using Gradient Vector Flow (GVF) snake and stepwise merge rule.
Segmenting blast cells from peripheral blood smears poses a significant challenge due to various factors, including no difference between the objects in the picture and the background, and there is sensitivity to noise. Many existing methods struggle to effectively handle the complexities inherent in such images. Therefore, there is an urgent need to develop innovative and robust techniques specifically tailored for this task.
In this research, an automatic system is developed to diagnose Acute Leukemia, addressing the significant challenges observed in the segmentation and feature selection of blood smear images. The complexity of efficiently segmenting blood cells and selecting pertinent features has hindered accurate diagnosis. To surmount these challenges, the study proposes leveraging flow cytometry test results instead of directly analysing blood cell images. This method aims to increase the accuracy and reliability of Leukemia diagnosis by using detailed cellular information provided by flow cytometry, thus bypassing image analysis problems.
