Automatic cell identification and analysis on in vivo reflectance confocal microscopy images of the human epidermis

Abstract: Reflectance confocal microscopy (RCM) allows real-time in vivo visualization of the skin at cellular level. The study of RCM images provides information on the topological and geometrical properties of the epidermis. These may change in each layer of the epidermis, depending on the subject's age and the presence of certain dermatological conditions. Studying RCM images requires manual identification of cells to derive these properties which is timeconsuming and subject to human error, highlighting the need for… Show more

“…This work is in accordance with prior published work 27 and extends it by studying a broader age range across thousands of images. Using a novel approach for automated keratinocyte detection on RCM images 8 allowed us to quantitatively study epidermal cells spatial organization in different settings.…”

“…Subsequent analysis was focused only on images of the SG and SS, in which individual viable keratinocytes could be observed and were characterized by a grainy cytoplasm surrounded by bright, grainy membranes, forming a honeycomb pattern. 12,13 Further image analysis was conducted using a three-step approach 8 based on the intensity and morphological features (membrane thickness, length, and keratinocyte size) of keratinocytes visible in RCM images (Figure 1). The first step of the image analysis workflow was to identify and separate the regions of interest (ROI) of tissue containing keratinocytes from the dark background (microrelief lines).…”

“…Unfortunately, image quality, heterogeneity, and low signal-to-noise ratio are a hurdle to automated methods’ development. Attempts at automating keratinocyte identification on RCM images have been made and were based on the identification of cell morphological features, e.g., membrane size, 9 , 10 but are hindered by manual parametrization often different among datasets, image types, and epidermal layers. Deep learning methods could be an alternative solution to circumvent these problems.…”
