Kvasir-Sessile Dataset Images: 196 endoscopic images Structure: images/ - Original endoscopic images masks/ - Segmentation masks (196 masks) Focus: Sessile (flat) polyp detection Purpose: Complementary training data for enhanced polyp detection Dataset Details CSV File The dataset_details.csv contains metadata for all 1,196 images: Columns: dataset - Source dataset (kvasir-seg or kvasir-sessile) image_filename - Image file name image_path - Full path to image mask_path - Full path to corresponding mask image_width - Image width in pixels image_height - Image height in pixels image_size_bytes - Image file size mask_size_bytes - Mask file size has_mask - Whether mask exists (Yes/No) num_bounding_boxes - Number of bounding boxes per image bounding_boxes - Bounding box coordinates (for kvasir-seg) label - Polyp label bbox_width / bbox_height - Bounding box dimensions Dataset Characteristics Image Resolutions: Common sizes: 528×622, 530×622, 546×626, 531×570 pixels High-resolution examples: 1070×1348, 1011×1220 pixels Standardized to 512×512 for training (as per project documentation) Polyp Distribution: Most images contain 1 polyp Some images contain multiple polyps (2-11 bounding boxes) All images are labeled as "polyp" (positive cases) Annotation Types: Segmentation Masks - Pixel-level polyp regions (binary masks) Bounding Boxes - Rectangular coordinates (kvasir-seg only) Labels - Polyp classification Usage in
