4、执行“滤镜-扭曲-旋转扭曲”命令,在弹出的对话框中将“角度”设置为-999度,最终如下图:
5、按下快捷键ctrl E合并“背景”图层和“图层1”得到合并的“背景图层”,如图:
6、执行“滤镜—像素化—彩色半调”命令,在弹出的对话框中设置各项参数,如下图:
7、执行“选择—色彩范围”命令,在弹出的对话框中设置各项参数,并单击画面中的圆形图像,将白色区域载入选区,如下图:
8、新建图层1,按下D,颜色设置为默认色,,按下快捷键Ctrl Delete将选区填充为白色,再按下快捷键Ctrl
D取消选区,选择背景图层,按X键换前景色和背景色,再按快捷键Ctrl Delete将选区填充为黑色,效果如下:
9、执行“图像-模式-RGB颜色”命令,在弹出的对话框中,单击“不拼合”按钮,图像将自动由“灰度”转换为“RGB颜色”颜色模式。
10、将前景颜色设置为(R102 G10 B137),单击“油漆桶工具”填充色彩,效果如图:
11、将前景色设置为(R232 G16 B143),复制图层1,得到图层1副本,点击“图层1副本”的缩略图将图像载入选区,按快捷键Alt Delete填充选区,再按下快捷键Ctrl D取消选区。再复制“图层1”得到“图层1副本2”,执行“编辑-自由变换”命令,适当调整图像的大小和位置。时尚背景要素制作就基本完成了。
下面是画正圆图形做出来的例子,不过它需要用涂抹工具进行调整,大家可以试试。

Diffusion can not only imitate better, but also "create". The diffusion model (DiffusionModel) is an image generation model. Compared with the well-known algorithms such as GAN and VAE in the field of AI, the diffusion model takes a different approach. Its main idea is a process of first adding noise to the image and then gradually denoising it. How to denoise and restore the original image is the core part of the algorithm. The final algorithm is able to generate an image from a random noisy image. In recent years, the phenomenal growth of generative AI has enabled many exciting applications in text-to-image generation, video generation, and more. The basic principle behind these generative tools is the concept of diffusion, a special sampling mechanism that overcomes the limitations of previous methods.

Kimi: In just one sentence, in just ten seconds, a PPT will be ready. PPT is so annoying! To hold a meeting, you need to have a PPT; to write a weekly report, you need to have a PPT; to make an investment, you need to show a PPT; even when you accuse someone of cheating, you have to send a PPT. College is more like studying a PPT major. You watch PPT in class and do PPT after class. Perhaps, when Dennis Austin invented PPT 37 years ago, he did not expect that one day PPT would become so widespread. Talking about our hard experience of making PPT brings tears to our eyes. "It took three months to make a PPT of more than 20 pages, and I revised it dozens of times. I felt like vomiting when I saw the PPT." "At my peak, I did five PPTs a day, and even my breathing was PPT." If you have an impromptu meeting, you should do it

In the early morning of June 20th, Beijing time, CVPR2024, the top international computer vision conference held in Seattle, officially announced the best paper and other awards. This year, a total of 10 papers won awards, including 2 best papers and 2 best student papers. In addition, there were 2 best paper nominations and 4 best student paper nominations. The top conference in the field of computer vision (CV) is CVPR, which attracts a large number of research institutions and universities every year.

After rain in summer, you can often see a beautiful and magical special weather scene - rainbow. This is also a rare scene that can be encountered in photography, and it is very photogenic. There are several conditions for a rainbow to appear: first, there are enough water droplets in the air, and second, the sun shines at a low angle. Therefore, it is easiest to see a rainbow in the afternoon after the rain has cleared up. However, the formation of a rainbow is greatly affected by weather, light and other conditions, so it generally only lasts for a short period of time, and the best viewing and shooting time is even shorter. So when you encounter a rainbow, how can you properly record it and photograph it with quality? 1. Look for rainbows. In addition to the conditions mentioned above, rainbows usually appear in the direction of sunlight, that is, if the sun shines from west to east, rainbows are more likely to appear in the east.

We know that LLM is trained on large-scale computer clusters using massive data. This site has introduced many methods and technologies used to assist and improve the LLM training process. Today, what we want to share is an article that goes deep into the underlying technology and introduces how to turn a bunch of "bare metals" without even an operating system into a computer cluster for training LLM. This article comes from Imbue, an AI startup that strives to achieve general intelligence by understanding how machines think. Of course, turning a bunch of "bare metal" without an operating system into a computer cluster for training LLM is not an easy process, full of exploration and trial and error, but Imbue finally successfully trained an LLM with 70 billion parameters. and in the process accumulate

Editor of the Machine Power Report: Yang Wen The wave of artificial intelligence represented by large models and AIGC has been quietly changing the way we live and work, but most people still don’t know how to use it. Therefore, we have launched the "AI in Use" column to introduce in detail how to use AI through intuitive, interesting and concise artificial intelligence use cases and stimulate everyone's thinking.
