Appropriate selection of features may lead to the specificity of classification methods and identify the most critical features from all sparse or dense impact data using a filter based on the recognition selection method characterized. Filtration is used to reduce sample complexity, improve the clarity of viscous samples, and reduce background signals, resulting in increased signal-to-noise ratios in analytical tests. Depending on the filtration method applied, particles are separated based on properties such as size. This study assessed the impact of filter selection and the variation in the number of projections on the final reconstructed artificial phantom images. Utilizing image reconstruction techniques, it delves into the application of mathematical transforms, including Radon and Fourier, to improve image quality and resolution, particularly in medical imaging modalities such as CT and MRI. The research predominantly focuses on the application of the Filtered Back Projection (FBP) algorithm to reconstruct images from changing numbers of projections. The results underscore the main role of filter choice in removing noise, with the Ramp filter presenting the most promising results. The investigation concludes that reducing the number of projections results in a decline in image contrast and an increase in image noise.

ABSTRACT: This article presents a preliminary report that uses minuscule images of blood tests to develop a diagnosis of leukemia. Examining through images is crucial since illnesses can be recognized and examined at an earlier stage using the images. The framework will be centered on leukemia and white blood cell illness. In fact, even the hematologist has trouble organizing the leukemic cells, and manually arranging the platelets takes a long time and is quite loose. In this way, early detection of leukemia recurrence allows the patient to receive the appropriate treatment. In order to address this problem, the framework will make use of the capabilities in small images and examine surface, geometry, shading, and quantifiable investigation modifications. These features' variations will be utilized as the classifier input. has transformed the use of images K proposes that (NN) and agglomeration. Examining a wide range of failure measures and increasing the intricacy of every system, the findings are examined. Utilizing feedforward (NN), image division is accomplished with less noise and a very sluggish conjunction rate. K-means agglomeration and (ANN) are intentionally used in this analysis to create a collection of processes that will work together to produce a much better presentation in (IS). An analysis has been conducted to determine the best rule for (IS).

This study analyzes the use of Computer-Supported Collaborative Learning (CSCL) in computer laboratory settings for secondary school science education. The literature review evaluates the impact of collaborative methods using computer simulations, virtual experiments, and other digital technologies. The search yielded 33 relevant studies, indicating that collaborative conditions outperformed individual laboratory work in computer environments across various measures. Collaborative work in pairs or small teams has been shown to lead to better learning outcomes and expert-like reasoning patterns. Additionally, students have reported finding collaborative computer laboratory work more enjoyable, engaging, and preferable to independent work. The integration of computer-supported collaborative learning (CSCL) into science education presents opportunities to enhance students' learning experiences through interactive and collaborative approaches. This study highlights the importance of student-centered learning design, effective group dynamics, and reliable technology infrastructure for successful CSCL implementation. Additional research is required to identify the best group composition and task design, as well as the implications for effectively implementing computer-supported collaborative learning in science laboratories
