【他們就這樣看了 90 分鐘的光頭…】蘇格蘭 AI 攝影機誤把裁判的光頭當足球跟拍轉播

【為什麼我們挑選這篇文章】AI 可以幫助處理繁瑣的事物,包含在跟拍球場上移動快速的足球。只是當蘇格蘭人們配合防堵疫情,唯一觀看球賽的管道只有這有這台直播時,這個跟拍 AI 犯的錯簡直不可饒恕啊。(責任編輯:鍾佳瑀)

用 AI 來直播足球比賽,會是怎樣一種體驗?
現在,真有一家蘇格蘭足球俱樂部引入了 AI「攝影機」。
該俱樂部驕傲地宣稱,此 AI 能自動追蹤足球在球場上的蹤跡,讓因疫情無法親臨現場的球迷,穩坐家中也不錯過任何一個精彩瞬間。
 但就在最近一場比賽上,這位 AI 攝影師遇見了它的一生之敵—— 一位光頭裁判(邊線裁判,lineman)。
註:足球比賽中,Lineman 為判定球是否出界,又稱為線審、邊線裁判、巡邊員。以下以邊線裁判/裁判簡稱。
 先來一起複習一下現場。
一開始,一切都顯得很正常,雙方球員退到中場等待門將開球,鏡頭也緩緩拉遠。
但當邊線裁判入鏡,場面就有點不太對了。
 AI 突然就放棄了看球,把鏡頭對準邊線裁判的腦袋。
這場面就有點尷尬了,趕緊人工修正一下。
小失誤,小失誤,我們接著來看比賽。
這是一個界外球。球員將球擲回場內,雙方正在激烈地爭搶……哦不,光頭裁判再次入鏡……嗯,我們看不到場上的那顆足球經歷了什麼,只能從裁判帥氣的揮旗中推斷一二。
人工校正也不能阻止這隻 AI 對光頭的執著……
於是,在家裡觀看這場比賽的球迷,90 分鐘的大部分時間里其實一直在圍觀邊線裁判的光頭,甚至連球是怎麼進的都沒看著……
看來是時候要求裁判必須要戴帽子或假髮了。
有球迷在看完這場比賽後,如是說道。還有球迷吐槽,科利納還好退得早,齊達內看了想舉報。
在 hacker news 和 reddit 等技術社區中,網友們也對這場「精彩」的比賽直播展開了熱烈的討論。
有網友表示,根據他的經驗,光頭、足夠亮的白鞋、燈光、比賽場地旁訓練場上的球、球員用來熱身的球,都是訓練 AI 時需要考慮的干擾因素。
對此,有網友笑稱,看來需要的不僅「這是球」數據集,還需要一個「這不是球」數據集。

比如這種:
而面對 AI 如此犯傻的表現,也有網友直接開了嘲諷模式:
我看把足量放射性材料塗在球上,用伽馬相機追蹤效果會更好。
還有網友建議,看來 AI 偏愛禿頭,科技公司應該聘請更多禿頭人才來提高多樣性。
總之這一次,只能說 AI 還有很大提升空間了。
你覺得呢?

longtailbutterfly, an NSF serving in SCDF, shares a day in his life on Reddit. Thank you for your service.

"Let's tell a story.
I'm working my 24 hr (work 24 hours, off 48 hours) duty. It's 1100 and I just finished morning lecture (equipment drill and familiarisation) in the engine bay of my fire station. It's a Saturday so our rota (platoon-ish) orders nasi lemak. Coding comes in over the loudspeaker and we turn out to a case of locked door, suspected DOA (decomposing body). Traffic doesn't give way to our LF (red rhino), as per usual (smh). We arrive at the HDB unit and instantly we smell the dead body. The knowledge of smell will come with experience. The niece, who called 995, asks me if her uncle will be ok. I already know the body is decomposing but I reply "We're unsure, but we'll try our best". I lie to her face. My pump operator (PO, and the only regular in the crew) looks at me and grimaces. We've been in this situation together many times before. We easily break the door and the smell intensifies. I go in first, followed by the ambulance (alpha) paramedic. We find the body on the bed in the master bedroom. The paramedic tells me, "About two weeks". The body is severely bloated, skin green and black. The face is unrecognizable as it has bloated too much. Bile attempts to escape from between the discolored lips creating bubbles. The smell is sweet but rotten and my fireman gags. I get the relevant information I need and step out for a breather. The niece looks at me and asks what is going on. I look at her and I know she knows he's dead. "You uncle... has passed away". I turn away to avoid the emotions. Emotions are killers in this line of work.
We get back in time for nasi lemak lunch. The chicken is a bit soggy this week. The smell of rotten flesh lingers in my nostrils. I watch the Malay romantic drama that my enciks chose on the TV. It's ok, the girl is cute.
Before dinner we get another call - unit fire confirm case. We race there and reach before the fire engine (pumper). They're caught in traffic and will take another few minutes. Two firefighters and I proceed to the unit. Instantly the thick black smoke chokes my throat and waters my eyes. I struggle with my breathing cylinder because the air hose delivery tool is stuck between my backplate and my back. I say fuck it, neighbours are already screaming for us to hurry. The pressure escalates but I close myself off from the members of public, just like normal. We all focus. The only things I listen to are my matra (radio) and my fireman. I just wear my facemask for minimal protection and crawl in. The fire is well alight on the stove and I shoot at it. The smoke limits my visibility to 0, I now can't see my fingers as I stretch out my arm. I crawl back out and get stuck on a fallen wire. I panic as I think of my family. Emotions are dangerous. A fire biker crawls in and frees me. We step out and I tell the crew the fire is almost finished but our CAF backpacks are finished (water foam sprayers). I send the firefighters down to set up water supply from hydrant and crawl back in with the firebiker. The smoke makes it feel like someone just threw hot ash down my throat. We extinguish the fire using an ass-washing hose from the kitchen toilet. I am coughing badly but he sprays my face with the hose. The kitchen is badly burnt. I can feel the smoke damage in my lungs. The owner and neighbours pat me on the back and thank me for saving their home as I walk out. I smile but I know I took another step closer to death.
We get back at 2200 and order McDonalds. It is the best Double McSpicy I’ve eaten in a while.
At lunch the next day my friend (SAF LTA) tells me how stressful being an instructor at SAFTI has been recently. I remember as my cylinder got trapped on the fallen wire, and how I thought of my family in those few struggling seconds. I nod my head and grunt. " SAF has it tough with JCC and everything huh?" I joke. He agrees enthusiastically.
All in a day’s work for the NSFs in SPF/SCDF. If we fail, someone dies from our direct actions. Welcome to NS. No second chances or semula. Just death. I wish the public knew the risks that some NSFs take each day. We might not be as fit as NDU or as garang as commandos, but we put our lives on the line literally every day.
As an NSF I can say I have saved many lives, fought many fires and contributed to Singapore. No play acting or training for a war that will never happen (though I understand the incredible need for an armed military). I love my job, I love NS and wouldn't trade it for anything else (maybe an EMT vocation).
I am still amazed that many members of public still associate NS with army. I wish people would know. There's no greater feeling in this world than knowing some uncle I helped rescue on my first duty at 0200 will live to eat his favourite mee pok or talk cock with his kakis because of my direct actions. Pride and care right?
At least I get paid $1400 a month (;
UPDATE: Thanks for overwhelming suppourt. If I knew how big this would get I would have proofread my writing more 😒 (some might say it spread like fire in dry grass during lalang season). I would tell more stories but I know that it would compromise my anonymity so I'll just shut my mouth, and unfortunately since this is a throw away you guys probably won't be hearing from me again.
What were my goals for this post?
To bring awareness to the nature and extent of NSF work in SCDF.
To just get some words off my chest.
This post was NOT meant to:
Bash SAF. I know the importance of a trained military (I believe I addressed this point in my initial post). If we didn't have the National Service Scheme, invading Singapore as Indonesia or Malaysia would be easy af.
Over-dramatise our work. I tried my hardest to write from a neutral stand point and deliver facts about incidents as cold, hard, and true as the Ben&Jerrys ice cream in my freezer however what we do on a daily sometimes makes me ask "Am I in a Michael Bay film?". It happens to the best of us.
If you were offended, I apologise. My intentions were merely to raise awareness for the often overlooked and under-praised "little brother" NSFs in SCDF/SPF. So many of our kind deserve recognition for what they deal with.
One last short bit before signing off.
EMTs (medical assistants in ambulances) have some of the roughest calls out there, no contest. I was having dinner with my buddy from BRT who later became an EMT at a high volume station when he dropped Fat Man 2.0 on me. Traditionally he and I have always been tuned to similar wavelengths as the chaos-utopia nature of our jobs is only shared between a select few.
He's an NSF like me -- 18-22, male, horny. As per the norm we were sharing gossip about events or big incidents in the Force, latest happenings and where that one cute paramedic at 33 is now. We were just digging in to our chow when he told me "I had a casualty die in my hands for the first time".
According to him it's not common for that to happen. I nod my head as I spool my pasta. It's has a thick green sauce and I can't help but think of my last DOA. I throw the idea out of my mind. Work is work, recreation is recreation. Usually when EMS arrives the casualty has a high chance of surviving, albeit sometimes with long lasting or even permanent injuries, or the casualty is dead. "Case of fall from height. The skull was completely smashed," he told me between mouthfuls of food, "I had the guy in a head grip but the harder I held his skull, the more my fingers just... pressed into his brain. There was no structural integrity left in the skull." We continued eating, he had told me of a similar case before. It wasn't new news to either of us. The pasta burns my tongue and I sip on my lemon tea. Too sweet. "Then he just stopped breathing. CPR AED didn't work." It was the first time witnessing the transition from alive to dead. They couldn't resuscitate. We paid the bill and started chitchatting about soccer on the way to the MRT. It was one of eight calls on his 8 hour duty. The food place was way too expensive and I made a mental note to never go back (unless I'm with my parents). Who charges $5 for ice lemon tea? Christ.
There are many duties where I don't get a call the whole 24 hours. If it's a busy day we'll get 3-4. 3-4 for him is a light day. Alpha (ambulance) guys really get it the hardest.
If you know someone who has a similar job, just listen to what they have to say. It's not easy for everyone to transition from seeing a broken family outside a unit containing a dead body to eating breakfast with their fam at their favourite prata house while being all happy smiley. We all get desensitised to death and risking everything but desensitisation doesn't mean it doesn't take a mental toll on our minds and well-being. We don't admit it because it's not garang, but everyone needs to get their thoughts off their chest every once in a while. You can help them by lending a ear (or a hug)."
