- 详细介绍:1956年湖南望城县安庆乡正在举办黄荷坝小学毕业生文艺汇演,雷正兴将受尽欺凌的渔家小姑娘演绎的有血有肉,惟妙惟肖。台下的六叔公六叔奶奶看得也是热…
3月3日,由新华社媒体融合生产技术与系统国家重点实验室联合中科汇金数字科技有限公司、中国传媒大学、南京理工大学唐金辉科研团队等单位共同修复的经典黑白电影《雷锋(田亮 饰)》完成4K高清上色与声音修复。在数字化技术的还原下,老电影焕发新光彩,可亲、可敬、可爱、可学的雷锋形象以更鲜活的方式与观众重逢。
今年是毛泽东等老一辈革命家为雷锋同志题词六十周年。60年来,雷锋精神历久弥新,学雷锋活动在全国持续开展,讲述雷锋故事的文艺作品层出不穷。电影《雷锋》由八一电影制片厂于1965年摄制完成,是我国第一部以雷锋事迹为题材、最早在银幕塑造雷锋艺术形象的影视作品,选取其短暂一生的几个主要片段,集中而生动地再现了他艰苦朴素、乐于助人的高尚品德,对宣传雷锋事迹、弘扬雷锋精神起了重要作用。
日前,习近平总书记对深入开展学雷锋活动作出重要指示强调,新征程上,要让学雷锋活动融入日常、化作经常,让雷锋精神在新时代绽放更加璀璨的光芒。历时近两年完成的电影《雷锋》超高清修复项目,运用自主研发的智能影像修复系统和单声道增强环绕声技术,传承红色基因,讲好红色故事,对红色经典电影超高清视听修复生产工艺进行了有益探索。
“老电影拍摄条件有限,胶片退化、受损严重。以往的单帧修复效率较低,通过自主研发的去噪、生成等修复算法,能有效解决60%的问题,但复杂场景仍然需要更精细的算法。”据中科汇金影像修复负责人熊志远介绍,同时,如何实现黑白电影精准上色是修复过程中的主要挑战。
针对电影《雷锋》中高速运动、低光照等复杂场景,团队运用自研的双向着色算法、高速光流算法、光照增强算法等,达到了更加准确的上色效果,显著提升了视频质量。在声音表现方面,该项目将原来的单声道分离出来,通过均衡调整、低频补偿等手段,全面提升了老影片的音质和观影沉浸感。
据了解,修复完成的电影《雷锋》将于今年在各大平台上映,届时,广大观众可一睹这部红色经典影片的全新风采。
