Adobe Photoshop vs OpenPano

Adobe Photoshop provides tools for creating, editing, and designing images and graphics. Its listed capabilities include batch editing, RAW photo support, layers, masking, AI retouching, and cloud sync. Users can combine, edit, and blend images and graphics; Firefly-powered Generative Fill, Generative Expand, and Remove Tool are among its AI features. Harmonize matches lighting, shadows, colors, and other details when blending people or objects into backgrounds, and a Topaz Labs partner model is available for image upscaling. Photoshop runs on Android, iOS, macOS, the web, and Windows. The browser-based version is included in Photoshop plans, while standalone mobile apps for iPhone and Android are free, with premium features available by subscription. Photoshop can be purchased by itself or as part of a multi-app plan. The listed plans include cloud storage, app access, and generative credits in different combinations; prices are not provided. A 7-day trial is listed.

OpenPano is a free C++ program for automatic panorama stitching, written from scratch without computer vision libraries. It offers cylinder, camera estimation, and translation modes, each with requirements for image capture or ordering. Its listed techniques include SIFT features, RANSAC-based homography or affine transformations, focal estimation, bundle adjustment, and straightening. The program supports Linux, macOS, and Windows. Build instructions use CMake and make for Linux, macOS, and WSL, and describe a Visual Studio 2015 process for Windows. Eigen and FLANN are build dependencies; libjpeg and CImg are optional image input/output components. The README recommends manually downscaling images of four megapixels or more to save time. Wide-angle images with heavy distortion may not work well unless camera parameters are used to undistort them. Memory use can be large with the default libc allocator; LAZY_READ can reduce it with a minor slowdown.
