numimages

Numimages is a common variable name used in programming and data processing to denote the number of images in a collection, sequence, or dataset. It is not a formal standard term but a descriptive identifier used in code, logs, and documentation. Variants include num_images or image_count.

In practice, numimages is assigned from the size of a collection, such as the length of a list of image paths, the number of image files in a directory, or the first dimension of a tensor representing a batch of images. For example, a tensor with shape [N, H, W, C] uses N as the number of images, which often equals numimages in many workflows.

Common usage includes iterating over images: for i in range(numimages): ...; loading data with a data loader that uses numimages to know when to stop. It may also be used to report dataset size in summaries or to partition data into training, validation, and test splits.

Type and constraints: numimages is typically an integer greater than or equal to zero. It should reflect the actual dataset size or the current view of the data. Mismatches between numimages and the real data can lead to out-of-range errors or skipped samples, especially when the dataset changes dynamically.

Variations and related terms: numframes (for video frames), image_count, dataset_size, n_images, batch_size. In software projects, the exact meaning is often described in code comments or project documentation to avoid ambiguity.
