La biblioteca incluye optimizaciones adicionales para mejorar la eficiencia de codificaci\u00f3n, permitiendo un aumento del 35% en la tasa de compresi\u00f3n de im\u00e1genes de alta calidad en comparaci\u00f3n con los c\u00f3decs JPEG tradicionales. En comparaci\u00f3n con libjpeg-turbo, la biblioteca jpegli logra un nivel de calidad similar mientras reduce el bitrate en un 32%. A nivel de API y ABI, la biblioteca es completamente compatible con libjpeg62 y puede ser utilizada como un reemplazo transparente. El c\u00f3digo de la biblioteca est\u00e1 escrito en C++ y se distribuye bajo la licencia BSD.    <center><img decoding=\"async\" alt=\"Google ha presentado la biblioteca jpegli para una compresi\u00f3n m\u00e1s eficiente de im\u00e1genes JPEG \" src=\"\/wp-content\/uploads\/2024\/04\/87616afdda6ac06e1275af421e05fb2c.png\" style=\"display:block;margin: 0 auto;\" \/><\/center>    <\/p>\n<p>El aumento del nivel de compresi\u00f3n se logra mediante el uso de tecnolog\u00edas avanzadas para reducir el ruido en la imagen y mejorar la calidad, aplicando m\u00e9todos de modelado psicovisual m\u00e1s eficaces para disminuir los artefactos que se generan. En particular, jpegli utiliza una heur\u00edstica de cuantificaci\u00f3n adaptativa, empleada por el proyecto JPEG XL, as\u00ed como algoritmos mejorados para la selecci\u00f3n de matrices de cuantificaci\u00f3n y el c\u00e1lculo de resultados intermedios.       <\/p>\n<p>La biblioteca jpegli permite codificar im\u00e1genes utilizando 10 o m\u00e1s bits por componente de color. A su vez, el resultado de los nuevos algoritmos de codificaci\u00f3n se adapta al modelo tradicional del formato JPEG, que solo permite el uso de 8 bits por componente de color. Esta caracter\u00edstica permite mantener la compatibilidad con los decodificadores existentes dise\u00f1ados para la representaci\u00f3n de color de 8 bits.        <\/p>\n<p>Las im\u00e1genes codificadas con jpegli cumplen completamente con el est\u00e1ndar JPEG, no requieren decodificadores espec\u00edficos y pueden ser visualizadas en los visualizadores JPEG existentes y en navegadores web. El uso de un decodificador propio para descomprimir im\u00e1genes comprimidas con jpegli permite lograr una reducci\u00f3n adicional de artefactos. La velocidad de codificaci\u00f3n con jpegli es comparable a las bibliotecas libjpeg-turbo y MozJPEG.<br \/>\n<br \/>Fuente: <a content=\"nofollow\" rel=\"nofollow\"
