Applications for image analysis can be found in many different industries, including robotics, surveillance, agriculture, Pharmaceutical and more. Many software companies like ImageProVision Technology are focusing on offering consumers tailor-made solutions and services to enhance image analysis services.

Image analysis is fundamentally the processing and interpretation of images through the use of algorithms and procedures. It includes a broad range of operations, such as picture augmentation, segmentation, feature extraction, object recognition, and image classification.

• Image Acquisition:
  Before beginning image analysis, images must first be obtained from a variety of sources, including digital cameras, satellites, MRI machines, scanner and video feeds. The attributes and quality of the obtained photos can have a big impact on the rest of the study.
• Pre-processing:
  Noise, artefacts, and consistency issues frequently plague raw photos. Images are pre-processed using methods like noise reduction, picture registration, and colour correction to enhance their quality and prepare them for future study.
• Segmentation:
  Segmentation is the process of separating an image into useful areas or objects. By isolating particular areas of interest, making subsequent analysis tasks easier, and enabling object-level knowledge, it plays a crucial part in image analysis.
• Feature extraction:
  Feature extraction is the process of identifying measurable aspects of an image that can be used to distinguish between various objects or regions. Different methods are used to extract features from photographs, such as texture, shape, colour, or spatial relationships.
• Object recognition:
  Object recognition seeks to locate and categorise certain objects or patterns in a picture. Matching extracted features against a set of predetermined templates is required for this activity, or machine learning algorithms can be used for object detection and recognition.
• Image classification:
  This entails categorising photographs into predetermined groups depending on the content of the images. By reaching astounding accuracy in tasks like facial recognition, object detection, and scene interpretation, machine learning techniques such as deep learning and convolutional neural networks (CNNs) have revolutionised the classification of images.
