    Liver tumor segmentation(LiTS) is a critical task in medical imaging analysis, playing a key role in the early detection, diagnosis, and treatment planning of liver diseases. Accurate segmentation of liver tumors from medical images is vital for quantifying tumor size, monitoring disease progression, and assessing treatment outcomes. However, manual segmentation is time-consuming and subjective, highlighting the need for automated and reliable deep learning-based methods. This study aims to evaluate and compare the performance of deep learning architectures: U-Net and its variants (U-Net, U-Net++, and newly introduced U-Net Square, and U-Net Cube) for segmenting liver tumors using medical imaging data. Each variant’s unique architectural modifications are examined, emphasizing their potential benefits for liver tumor segmentation tasks. The efficacy and performance of these models for detecting liver tumors is analyzed using metrics like Dice Coefficient. It is observed that basic U-Net outperforms other architectures in liver tumor segmentation. This study further provides potential implications for enhanced diagnostic accuracy and treatment planning in clinical practice. The results contribute valuable insights into the strengths and limitations of U-Net variants, assisting researchers in selecting optimal deep-learning models for liver tumor segmentation.

  • Agricultural Field Boundary Delineation Using Deep Learning Techniques
    Arbaz Sayed, Vidya Kumbhar, Swapnil Jadhav, and Sahil K. Shah

    IEEE
    Agriculture Stakeholders need to have a precise understanding of the field boundaries. This is a required resource for farm owners to onboard farms on modern farming software programs, it enhances multiple cropping categorization accuracies and it is used by government agencies to track incentives and food production, along with many other uses. The awareness of the location of fields on the farms is of great importance to a farmer. Even though this can be done for small farm holders by manually surveying the field but it is a very human resource-intensive and time-consuming task for huge farms. Knowing the partition of the fields by their serial number or name can significantly improve the management of fields especially when it is reaping season. Also, the boundary shapefiles can be integrated with a precision farming platform through which farmers can keep a track of all the activities taking place in all their fields, which was not possible before. The current study uses modern state-of-the-art techniques integrated with geospatial technology which helps to reduce the time required for the same process by 95%. The deep learning approach helped to achieve 93% accuracy over the manually drawn fields.

  • An approach towards text detection from complex images using morphological techniques
    Vyankatesh V. Rampurkar, Sahil K. Shah, Gyankamal J. Chhajed, and Sanjay Kumar Biswash

    IEEE
    Text information in natural scene images serves as important clues for many image-based applications such as scene understanding, content-based image retrieval, assistive navigation, and automatic geocoding. However, locating text from a complex background with multiple colors is a challenging task. Two different techniques using morphological operations are proposed to find text strings from any natural scene images. Proposed techniques are based on siblings' method i.e. adjacent character grouping method and text line grouping method. Text line grouping method can locate text strings situated at arbitrary orientations. Proposed techniques can find text strings by using structure-based partition and grouping methods using morphological operations. Proposed system strives toward Morphological methodologies that aid automatic detection, segmentation and recognition of visual text entities in complex several images and thus resulting in optimal performance as compared with existing techniques.
