A data analyst is preparing a large dataset of digital photographs for a computer vision model. The key requirement is to reduce the overall file size of the dataset to optimize storage and processing speed. A slight, often imperceptible, reduction in image quality is acceptable to achieve this goal. Which file format should the analyst use?
The correct answer is .jpg. JPEG (Joint Photographic Experts Group) files use a lossy compression method, which significantly reduces file size by permanently discarding some image data. This makes the .jpg format ideal for situations where minimizing storage and optimizing load times is critical, and a minor reduction in quality is an acceptable trade-off, especially for photographic images.
.png: This format uses lossless compression, which preserves all original image data, resulting in higher quality but also larger file sizes compared to .jpg. It is not the best choice when the primary goal is file size reduction.
.tiff: This format uses lossless compression or no compression at all, which preserves the highest image quality but results in very large file sizes. It is often used for professional printing and archiving, not for optimizing storage space.
.bmp: This format is typically uncompressed, leading to extremely large file sizes. It is unsuitable for this scenario where file size reduction is a key requirement.
