INVESTIGATION OF THE IMPACT OF DATA AUGMENTATION METHODS AND NOISE ON THE ACCURACY OF NUCLEI SEGMENTATION IN HISTOLOGICAL IMAGES USING A DEEP NEURAL NETWORK
Abstract. Segmentation of medical images is one of the key tasks of biomedical informatics, especially in the context of cancer diagnosis. The task of precise segmentation of cell nuclei is particularly relevant and necessary to identify morphological changes in tissues. However, the main challenges and problems in this area remain the variability of image quality, […]
STUDY OF COMMUNICATION IN VISIBLE LIGHT USING PIM AND PPM FORMATS FOR SIMULTANEOUS DATA TRANSMISSION
Abstract. A visible light communication system with simultaneous brightness control and data transmission is experimentally demonstrated in this paper. A pulse-width modulation (PWM) scheme is adopted for brightness control of the light-emitting diode and pulse- position modulation (PPM) superimposed on top of PWM is used for data communications. We show that independent control of light […]
