| Summary | 2712: Smart thumbnailing based on image content | ||||
| Description | We can integrate some third party code to get thumbnailing based on any of: - Most 'energetic' part of the image (CropEntropy: https://github.com/stojg/crop) - Faces (https://github.com/mauricesvay/php-facedetection [there's also a good Microsoft API and OpenCV PHP extension, but those are excessive - the PHP-based algorithm here is sound and a port of a popular JavaScript one]) We'd implement it as an extension of the 'where' parameter in the convert_image_plus function. Instead of start/end/both we provide a value of either 'energetic' or 'face'. These essentially detect a central point which becomes the crop/pad origin. | ||||

Further to defining the central point, we may also want to respect face width's/height's for the case of the face being bigger than the thumbnail. We'd need to do some pre-scaling down in the convert_image_plus function, so that what is passed through to convert_image has a face fitting the thumbnail with some spare. |
