kandi X-RAY | AFN Summary
Moire patterns are commonly seen artifacts when taking photos of screens and other objects with high-frequency textures. It's challenging to remove the moire patterns considering its complex color and shape. In this work, we propose an Attentive Fractal Network to effectively solve this problem. First, we construct each Attentive Fractal Block with progressive feature fusion and channel-wise attention guidance. The network is then fractally stacked with the block on each of its levels. Second, to further boost the performance, we adopt a two-stage augmented refinement strategy. With these designs, our method wins the burst demoireing track and achieves second place in single image demoireing and single image deblurring tracks in NTIRE20 Challenges. Extensive experiments demonstrate the superiority of our method for moire pattern removal compared to existing state-of-the-art methods, and prove the effectiveness of its each component.

QUESTION
I am having initialization trouble with an exchange rate structure. In the method getRates I have been trying to implement dictionary key / value logic to copy exchange rates into an ordered array. I am getting the error "Variable 'moneyRates' used before being initialized". I tried adding a memberwise initializer but was unsure how to initialize the rate array. I have also been wondering if I should move the instance of MoneyRates to the top of the class instead of in the getRates method.
...ANSWER
Answered 2021-Jun-10 at 04:47The error you are getting is because you declare the variable "moneyRates" but you do not instantiate it to something.
QUESTION
I have a question concerning modeling JSON data.
I am trying to figure out how to decode JSON exchange rate data. The JSON file consists of a date, base currency ("eur" in the example below), and some currencies with rates compared to the base currency. It would be a straight forward nested JSON object without the base currency, but with the base currency thrown in the middle without a key I'm not sure where to begin.
Do I need codingKeys for the base currency and rates? How do you handle the missing base currency key?
...ANSWER
Answered 2021-Jun-08 at 06:57Honestly for this particular JSON I'd use traditional JSONSerialization

I’m using the manifold.stream library to send a message through a websocket:
...ANSWER
Answered 2021-May-03 at 08:13Only you will be able to answer your question. The error means that there is already a process that is listining on that port. If you're running a Linux box, use lsof -i
(as root or using sudo
) to find out which process.
The most likely scenario is that you've run your code already. I.e., you'll find out that a Clojure process is still using that port. And this in turn can easily happen when you forget to stop the server before executing the start-server
again. According to the Aleph documentation on start-server
, you would need to call .close
on the server
var.
QUESTION
I need help with currency exchange rate lookup given a key (3 digit currency code). The JSON object is rather unusual with no lablels such as date, timestamp, success, or rate. The first string value is the base or home currency. In the example below it is "usd" (US dollars).
I would like to cycle through all the currencies to get each exchange rate by giving its 3 digit currency code and storing it in an ordered array.
...ANSWER
Answered 2021-Apr-29 at 01:13Thanks lorem ipsum for your help. Below is the updated ASI logic that copies the exchange rates to the rateArray using key/value lookups.
QUESTION
I'm attempting to use Stormcrawler to crawl a set of pages on our website, and while it is able to retrieve and index some of the page's text, it's not capturing a large amount of other text on the page.
I've installed Zookeeper, Apache Storm, and Stormcrawler using the Ansible playbooks provided here (thank you a million for those!) on a server running Ubuntu 18.04, along with Elasticsearch and Kibana. For the most part, I'm using the configuration defaults, but have made the following changes:
- For the Elastic index mappings, I've enabled
_source: true
, and turned on indexing and storing for all properties (content, host, title, url) - In the
crawler-conf.yaml
configuration, I've commented out alltextextractor.include.pattern
andtextextractor.exclude.tags
settings, to enforce capturing the whole page
After re-creating fresh ES indices, running mvn clean package
, and then starting the crawler topology, stormcrawler begins doing its thing and content starts appearing in Elasticsearch. However, for many pages, the content that's retrieved and indexed is only a subset of all the text on the page, and usually excludes the main page text we are interested in.
For example, the text in the following XML path is not returned/indexed:
(text)
While the text in this path is returned:
Are there any additional configuration changes that need to be made beyond commenting out all specific tag include and exclude patterns? From my understanding of the documentation, the default settings for those options are to enforce the whole page to be indexed.
I would greatly appreciate any help. Thank you for the excellent software.
Below are my configuration files:

ANSWER
Answered 2021-Apr-27 at 08:07IIRC you need to set some additional config to work with ChomeDriver.
Alternatively (haven't tried yet) https://hub.docker.com/r/browserless/chrome would be a nice way of handling Chrome in a Docker container.
