Hello my name is Libana Roscher

and I want to present our paper Controlled multimodal image generation for plant growth modeling

which was presented at the international conference on pattern recognition last summer.

So when we have a look at such an aquaculture field

and we work with robotics and with machine learning methods for phenotyping

we can ask ourselves different questions

so for example we can ask what is on the field

which is a typical classification task

or we can ask what is the yield in a specific area

which is a typical regression task

or we can ask ourselves what will a plant look like in the future

and this is a forecasting tasks

and this is exactly the question we addressed in our paper

so imagine the following scenario you already know that

when plants grow closely together this can be very beneficial

so for example it can increase the biomass the crucial question is now what is actually a good mixture

and so what you can do is you can test different mixtures then you can collect data

and then you can learn a model from this information

and this model relates the information from what we have measured to a parameter like the biomass

so you have a relationship between the mixtures and the biomass

and then the good thing is this model can be applied to new mixtures

and these new mixtures were not tested yet in the field before

so you get an idea what potential good mixtures are

And one problem is now that one might be interested in the biomass

and the other might be interested in the spread of diseases.

So it would be good to combine this and to get complete information.

And this can be done if you model the whole appearance with plants, that means if you generate images.

And with this you are flexible in what you do with the result

because it can be treated such as an artificial sensor measurement.

So in order to generate such images we used

so -called generative adversarial networks illustrated here and this is a neural network consisting of two parts.

So one part is the generator G and this generator is responsible to generate images.

The other part is the discriminator, and the discriminator helps to train the generator to generate really good images.

The discriminator does it by trying to distinguish between real images and images which were generated by the generator.

So in the best case, the generator generates such good images

that the discriminator can no longer distinguish between a real image

and an image which was generated but there's one crucial thing

which is important for our application

so we do not want only want to generate an arbitrary

nice -looking image we want to condition on specific factors on specific things

and one important thing is we want to condition on the appearance of an of an additional input image

which is from an earlier point in time

and the second important thing is we want to condition on

so -called factors of variation and these factors of variation are factors

which influence the appearance of the of the plants

and the novelty of our paper is exactly this part

because on the one hand we learned the representation

which is useful for the machine learning model but on the other side it was

Because we can also easily and intuitively change these factors of variation so that we can produce different scenarios, different outcomes.

And so here you can see results of

which we presented in our paper where we generated images with chain factors of variation.

So our dataset contains UAV images, which were captures in Kampus -Klein -Altendorf,

where we have different mixtures of spring wheat and faba bean.

And we also collected different factors of variation, which belong to these mixtures.

And they are illustrated in green and light blue and in dark blue.

And on the left, you can see the input image, which is from an early growth stage.

And this is the real scene from a later growth stage and the measured factors of variation.

And these images are all generated images.

So here we change the factors of variation.

So for example, on the very right image, you can see we set all factors of variation for Faba bean to zero.

And actually there are no Faba bean plants in the generated image.

So we can clearly control and manipulate how the images can be generated it

and from these images we can now derive specific parameters pointing

us to potential promising mixtures we can later test in the

field with this thank you very much for listening you can find the paper by scanning the qr code

and if you are more interested in this research direction you can go to our website

or you can have a look in my YouTube channel.

Thanks a lot!

本節課學習內容

通過觀看這段關於植物生長建模的科技影片，你將練習聽懂學術演講中的英語表達，同時提升影子跟讀法（shadow speak）的技巧。影片語速適中，用詞專業但清晰，非常適合訓練聽力和口語的同步性。跟著影片模仿發音、語調，還能積累科技領域的實用詞彙，一舉多得！

核心詞彙與短語

generative adversarial networks：生成對抗網路（AI領域術語，注意連讀發音）
factors of variation：變異因素（學術討論中常用，重音在“variation”）
phenotyping：表型分析（生物學詞彙，練習咬字清晰）
condition on：以……為條件（科技英語中表“基於”，注意介詞搭配）
forecasting task：預測任務（實用短語，適用於各類場景）

練習技巧

影片中演講者語氣平穩，語速中等，很適合影子跟讀法（shadowspeak）練習。建議先完整聽一遍，熟悉內容後，逐句暫停模仿：注意模仿重音和停頓，比如“the generator is responsible to generate images”中，“responsible”和“generate”要重讀。遇到長句（如介紹模型的部分），可拆分練習，先跟後半句，再連起來。每天堅持10分鐘，既能提高英語發音，又能熟練掌握學術英語的表達節奏。記住，犯錯是進步的開始，大膽開口，你會越練越棒！

看影片學英語就是這麼簡單，利用好這段素材，讓影子跟讀法成為你的口語提升利器吧！

影片中的語法

說話人最常用的結構，並附上影片中的原話：

結構	影片中的用法
被動語態 be + 過去分詞 — 強調發生了什麼，而不是誰做的	was presented · can be applied · were not tested
定語從句 who / which + 從句 — 補充說明人或事物	images which were · image which was · images, which were

什麼是跟讀法？

跟讀法 (Shadowing) 是一種有科學依據的語言學習技巧，最初開發用於專業口譯員的培訓，並由多語言者Alexander Arguelles博士普及。這個方法簡單而強大：您在聽英語母語原聲的同時立即大聲重複——就像是一個延遲1-2秒緊跟說話者的影子。與被動聽力或語法練習不同，跟讀法強迫您的大腦和口腔肌肉同時處理並模模擬實的講話模式。研究表明它能顯著提高發音準確性，語調，節奏，連讀，聽力理解和口語流利度——使其成為雅思口語備考和真實英語交流最有效的方法之一。
