1. 1. Generation of Synthetic White Blood Cell Images Using Denoising Diffusion

   University essay from Lunds universitet/Matematik LTH

   Author : Louise Zettergren; Fanny Nilsson; [2023]
   Keywords : Mathematics and Statistics;

   Abstract : CellaVision’s digital hematology systems are designed to analyze blood and pre-classify different types of blood cells. Some abnormal white blood cells are rare, which can cause imbalanced datasets. This can lead to a decrease in pre- classification performance and a need to carry out more time-consuming data gathering. READ MORE

3. 2. Detecting red blood cells and platelets in blood smears using a single multi-class object detector

   University essay from Lunds universitet/Matematik LTH

   Author : Timothy Burfield; Sophia Carlsson; [2022]
   Keywords : Mathematics and Statistics;

   Abstract : Blood analysis is an integral part of diagnostic medicine and used in most medical fields. The concentrations of red blood cells and platelets, and ratio between these, are used for diagnosing several diseases. CellaVision develops machines and software for automatically capturing images of blood sample smears and detecting its cellular contents. READ MORE

4. 3. Pre-classification of Hairy Cells Using Supervised Contrastive Learning

   University essay from Lunds universitet/Matematik LTH

   Author : Alexia Han; Rebecca Schömer Ericsson; [2022]
   Keywords : supervised contrastive learning; hairy cells; abnormal lymphocytes; deep learning; Cellavision; Xception; artificial neural network; convolutional neural networks; Mathematics and Statistics;

   Abstract : Differential of the peripheral blood is an important tool when assessing blood-related diseases. Lymphocytes are part of the immune system and morphological changes thereof should raise attention. READ MORE

5. 4. Domain adaptation for white blood cell classification - Bridging the gap created by optical hardware upgrades

   University essay from Lunds universitet/Matematik LTH

   Author : Elsa Lindhé; Erik Olsson; [2022]
   Keywords : Domain adaptation; leukocytes; WBC; machine learning; deep learning; Mathematics and Statistics;

   Abstract : Collecting enough labeled images to train an artificial neural network (ANN) is a common struggle since the process is tedious, time consuming and expensive. CellaVision, a company that creates analyzers that automate the process of finding and pre-classifying abnormal blood cells using machine learning, runs into this problem regularly. READ MORE

6. 5. Automatic Detection of Rouleau Formations Using Image Processing and Deep Learning

   University essay from Lunds universitet/Matematik LTH

   Author : Josefin Johansson; Oscar König; [2021]
   Keywords : object detection; image processing; deep learning; rouleaux; rouleaux detection; Mathematics and Statistics;

   Abstract : Analysis of peripheral blood smears is commonly used to aid physicians in diagnosing diseases, checking for infections and evaluating the function of organs. One object of interest in such analysis is the presence of red blood cell aggregates called rouleaux. READ MORE
