腐女

快科技8月24日消息，据阿里巴巴公众号消息，近期，阿里巴巴达摩院联合中国医科大学附属盛京医院等机构研发出肝癌诊断AI模型DAMO LiON，可通过CT影像识别微小的肝脏癌变病灶。    Costume designer Smriti Chauhan is one of the creative forces behind Ranveer Singh’s look in Dhurandhar. She says the film’s now-viral bearded avatar was born from months of iterative work, collaboration and a deep integration of costume with hair, makeup, lighting and performance. In an exclusive conversation with Filmfare, Chauhan breaks down the meticulous process, from conceptual sketches to 40-metre salwars and silicon jewellery designed to survive high-octane action.          Region, story and technical precisionChauhan reveals that the idea of a full beard was rooted in the character’s geography and cultural background. “We knew there was going to be a beard because of the region he comes from, what he’s performing and who he is,” she says. The hair and makeup team played a decisive role as well. They dictated the skin tone, lens colour and texture choices that needed to sync with her costume palette. “Costume and hair and makeup cannot be separated,” Chauhan emphasises. “The look comes alive only when all three, costume, HMU and lighting - work in harmony.”Ranveer’s inputs and a sharp eye for detailChauhan was nervous as she met Ranveer Singh for the first time while working on the movie. However, she says that the actor immediately put her at ease. But Singh was far from a passive participant. He dissected materials, cuts and accessories with precision. He’d ask, ‘Why linen? Why not silk? Why this jewellery? Why this structure?’ According to the designer, his questions pushed her to have solid answers.Smriti also shares, “And when you have the answers, it gives you more clarity. So with Ranveer, he ensured that he helps the two of us get clarity on the character. He also added some technical bits. He asked me to add a wire on the collar so that it stays like that when he is moving around.”          Ranveer’s physical transformationOne of the biggest challenges for Chauhan’s team was designing for a body that kept changing. Ranveer bulked up for a portion of the film and then shed weight rapidly for another. “We had to ensure that with every change in his body, the clothes didn’t show that change... The look had to stay consistent,” she shares.The character evolves from a street nobody to someone big. The costumes had to mirror his transformation. Initially, his look is rooted in ruggedness. “So all of this came together working very closely with him. We understood which materials are working the best and which is looking rugged. His entire journey in this film is like that of a nobody becoming somebody, like really big. So that journey itself was grand.”          The nightmare of action-friendly jewelleryLater, as the character rises in stature, accessories become key. Ironically, Chauhan had laughed off Ranveer’s early questions about accessories because of the heavy action sequences. But he persisted. “Cut to the first sequence in the teaser - he is loaded in accessories. I can tell you this, I’ll throw a rug on him and he’ll carry it with perfection. The next thing you know is that we have added so many accessories on him,” she adds.As the film is packed with lengthy action sequences, some shot over 10 to 12 days, Chauhan’s team had to create silicon jewellery that looked real but wouldn’t injure the actor or break under impact. “It was a nightmare but became necessary.”     The Balochi salwar challengeOne of the film’s most technically challenging pieces was the traditional Balochi salwar. The authentic garment uses 30 to 40 metres of fabric, which is impossible for action scenes. Instead, Chauhan’s team created prototypes using 17 to 20 metres. They experimented with fabric weight, fall, pleats and movement. “We kept making so many prototypes. When he wore it, it looked less; when we spread it out, it was huge. Overall, it was a massive learning experience,” she recalls.Months of prep, presentations and look testsThe team spent two to three months preparing Ranveer’s looks. They went through six different presentation decks and multiple iterations for each phase of his journey. Three comprehensive look tests were done even before shooting. Moreover, sudden scheduling changes accelerated everything. “We thought we’d shoot in October, but suddenly the shoot got pulled to July. We were like, ‘What?’ But luckily we had done early homework,” she recalls.The moment Ranveer called her a ‘Rockstar’Chauhan recalls one of her most overwhelming moments when Ranveer looked at the first major look test and told her he’d “never seen this level of detailing.” “Coming from someone who’s worked with the greatest designers worldwide, it meant the world. It pushed me to raise my own bar,” she says.Despite the scale, the pressure and the physicality of the film, Chauhan says Ranveer’s collaborative nature made the process smooth. “He is the best team player I could have asked for. His encouragement, his curiosity, his involvement - everything helped build the character’s world,” she quips.Also Read: Sara Arjun gives Dhurandhar co-star Ranveer Singh a moving tribute as she shares BTS photos。

B | 在两个月的真实世界前瞻临床试验中，DAMO LiON发现了15例原本被遗漏的恶性肿瘤，绝大部分为1厘米左右的病灶，帮助患者得到及时的手术或药物治疗。相关论文登上国际顶级学术期刊《自然·医学》（Nature Medicine）。据介绍，DAMO LiON模型作为“AI安全员”协助医生阅片，既能精准识别原发性肝癌，更擅长揪出容易被忽视的肝转移。

C | 实验结果显示，AI模型识别出恶性肿瘤的准确率高于放射科医生。

当医生用AI模型协助阅片，用时减少了27%，而对恶性肿瘤的敏感性更提高了11.5%，有效减少漏诊；在AI协助下，初级医生能达到资深医生水平。

D | 研究团队随后将AI模型实际部署到医院，参与日常阅片，当AI与医生初诊结论不一致时，病例会交给资深放射科医生复核，必要时升级至多学科团队（MDT）讨论。两个月内，AI共阅读1万多名患者的增强CT影像，辅助医生抓出15例原本被忽略的肝转移，推动改变了这些患者的治疗方案。据官方介绍，早在2017年，达摩院在行业内率先提出用AI识别医学影像中人眼难以察觉的细微病灶。目前已先后研发出基于平扫CT的胰腺癌筛查AI模型 DAMO PANDA、胃癌筛查AI模型DAMO GRAPE、肠癌筛查AI模型DAMO COCA等，相关成果三次登上《自然·医学》，进入国家药品监督管理局的创新通道，并获美国食品药品监督管理局（FDA）“突破性医疗器械”认定。
