  Lymphocytes, a type of leukocytes, play a vital role in the immune system. The precise quantification, spatial arrangement and phenotypic characterization of lymphocytes within haematological or histopathological images can serve as a diagnostic indicator of a particular lesion. Artificial neural networks, employed for the detection of lymphocytes, not only can provide support to the work of histopathologists but also enable better...

• Image Segmentation of MRI image for Brain Tumor Detection

  Publikacja

  • K. Ullah

  - Rok 2020

  this research work presents a new technique for brain tumor detection by the combination of Watershed algorithm with Fuzzy K-means and Fuzzy C-means (KIFCM) clustering. The MATLAB based proposed simulation model is used to improve the computational simplicity, noise sensitivities, and accuracy rate of segmentation, detection and extraction from MR...

  Renal tumor malignancy classification is one of the crucial tasks in urology, being a primary factor included in the decision of whether to perform kidney removal surgery (nephrectomy) or not. Currently, tumor malignancy prediction is determined by the radiological diagnosis based on computed tomography (CT) images. However, it is estimated that up to 16% of nephrectomies could have been avoided because the tumor that had been...

• Extraction of stable foreground image regions for unattended luggage detection

  Publikacja

  • G. Szwoch

  - MULTIMEDIA TOOLS AND APPLICATIONS - Rok 2016

  A novel approach to detection of stationary objects in the video stream is presented. Stationary objects are these separated from the static background, but remaining motionless for a prolonged time. Extraction of stationary objects from images is useful in automatic detection of unattended luggage. The proposed algorithm is based on detection of image regions containing foreground image pixels having stable values in time and...

• An Overview of Image Analysis Techniques in Endoscopic Bleeding Detection

  Publikacja

  • A. Brzeski
  • A. Blokus
  • J. Cychnerski

  - International Journal of Innovative Research in Computer and Communication Engineering - Rok 2013

  Authors review the existing bleeding detection methods focusing their attention on the image processing techniques utilised in the algorithms. In the article, 18 methods were analysed and their functional components were identified. The authors proposed six different groups, to which algorithms’ components were assigned: colour techniques, reflecting features of pixels as individual values, texture techniques, considering spatial...

• Overhead wires detection by FPGA real-time image processing

  Publikacja

  • P. Kowalski
  • R. Smyk

  - ITM Web of Conferences - Rok 2019

  The paper presents design and hardware implementation of real-time image filtering for overhead wires detection divided on image processing and results presentation blocks. The image processing block was separated from the whole implementation, and its delay and hardware complexity was analysed. Also the maximum frequency of image processing of the proposed implementation was estimated.

• Digital Fingerprinting based on Quaternion Encryption for Image Transmission

  Publikacja

  • B. Czaplewski
  • M. Dzwonkowski
  • R. Rykaczewski

  - Przegląd Telekomunikacyjny + Wiadomości Telekomunikacyjne - Rok 2013

  In this paper a new digital fingerprinting scheme for images is proposed. A proposed method is based on quaternion encryption with Cipher Block Chaining (CBC) mode of operation. Quaternions are hyper-complex numbers of rank 4 and thus often applied to mechanics in three-dimensional space. The encryption algorithm is designed for grey-tone images. For purpose of encryption, the algorithm uses the rotation of data vectors presented...

• Polymodal Method of Improving the Quality of Photogrammetric Images and Models

  Publikacja

  • P. Burdziakowski

  - ENERGIES - Rok 2021

  Photogrammetry using unmanned aerial vehicles has become very popular and is already commonly used. The most frequent photogrammetry products are an orthoimage, digital terrain model and a 3D object model. When executing measurement flights, it may happen that there are unsuitable lighting conditions, and the flight itself is fast and not very stable. As a result, noise and blur appear on the images, and the images themselves can...
