Open source! Beyond ZoeDepth! DepthFM: Fast and accurate monocular depth estimation! Open source! Beyond ZoeDepth! DepthFM: Fast and accurate monocular depth estimation! Apr 03, 2024 pm 12:04 PM

0.What does this article do? We propose DepthFM: a versatile and fast state-of-the-art generative monocular depth estimation model. In addition to traditional depth estimation tasks, DepthFM also demonstrates state-of-the-art capabilities in downstream tasks such as depth inpainting. DepthFM is efficient and can synthesize depth maps within a few inference steps. Let’s read about this work together ~ 1.

Use ddrescue to recover data on Linux Use ddrescue to recover data on Linux Mar 20, 2024 pm 01:37 PM

DDREASE is a tool for recovering data from file or block devices such as hard drives, SSDs, RAM disks, CDs, DVDs and USB storage devices. It copies data from one block device to another, leaving corrupted data blocks behind and moving only good data blocks. ddreasue is a powerful recovery tool that is fully automated as it does not require any interference during recovery operations. Additionally, thanks to the ddasue map file, it can be stopped and resumed at any time. Other key features of DDREASE are as follows: It does not overwrite recovered data but fills the gaps in case of iterative recovery. However, it can be truncated if the tool is instructed to do so explicitly. Recover data from multiple files or blocks to a single

Convert VirtualBox fixed disk to dynamic disk and vice versa Convert VirtualBox fixed disk to dynamic disk and vice versa Mar 25, 2024 am 09:36 AM

When creating a virtual machine, you will be asked to select a disk type, you can select fixed disk or dynamic disk. What if you choose fixed disks and later realize you need dynamic disks, or vice versa? Good! You can convert one to the other. In this post, we will see how to convert VirtualBox fixed disk to dynamic disk and vice versa. A dynamic disk is a virtual hard disk that initially has a small size and grows in size as you store data in the virtual machine. Dynamic disks are very efficient at saving storage space because they only take up as much host storage space as needed. However, as disk capacity expands, your computer's performance may be slightly affected. Fixed disks and dynamic disks are commonly used in virtual machines

How to restore chat spark on TikTok How to restore chat spark on TikTok Mar 16, 2024 pm 01:25 PM

On Douyin, a short video platform full of creativity and vitality, we can not only enjoy a variety of exciting content, but also have in-depth communications with like-minded friends. Among them, chat sparks are an important indicator of the intensity of interaction between the two parties, and they often inadvertently ignite the emotional bonds between us and our friends. However, sometimes due to some reasons, the chat spark may be disconnected. So what should we do if we want to restore the chat spark? This tutorial guide will bring you a detailed introduction to the content strategy, hoping to help everyone. How to restore the spark of Douyin chat? 1. Open the Douyin message page and select a friend to chat. 2. Send messages and chat to each other. 3. If you send messages continuously for 3 days, you can get the spark logo. On a 3-day basis, send pictures or videos to each other

Google is ecstatic: JAX performance surpasses Pytorch and TensorFlow! It may become the fastest choice for GPU inference training Google is ecstatic: JAX performance surpasses Pytorch and TensorFlow! It may become the fastest choice for GPU inference training Apr 01, 2024 pm 07:46 PM

The performance of JAX, promoted by Google, has surpassed that of Pytorch and TensorFlow in recent benchmark tests, ranking first in 7 indicators. And the test was not done on the TPU with the best JAX performance. Although among developers, Pytorch is still more popular than Tensorflow. But in the future, perhaps more large models will be trained and run based on the JAX platform. Models Recently, the Keras team benchmarked three backends (TensorFlow, JAX, PyTorch) with the native PyTorch implementation and Keras2 with TensorFlow. First, they select a set of mainstream
