Set High resolution programmatically. Camera mCamera = Camera.open(); Camera.Parameters params = mCamera.getParameters(); // Check what resolutions are supported by your camera List<Size> sizes = params.getSupportedPictureSizes(); // Iterate through all available resolutions and choos...

As described in the remarks section you can specify the Gradle version used by each project editing the Gradle distribution reference in the gradle/wrapper/gradle-wrapper.properties file. For example: ... distributionUrl = https\://services.gradle.org/distributions/gradle-2.14.1-all.zip ... ...

Like for 1D signals, it's possible to filter images by applying a Fourier transformation, multiplying with a filter in the frequency domain, and transforming back into the space domain. Here is how you can apply high- or low-pass filters to an image with Matlab: Let image be the original, unfiltere...

In [1]: import pandas as pd In order to run a query in BigQuery you need to have your own BigQuery project. We can request some public sample data: In [2]: data = pd.read_gbq('''SELECT title, id, num_characters ...: FROM [publicdata:samples.wikipedia] ...: ...

If you have created service account and have private key json file for it, you can use this file to authenticate with pandas In [5]: pd.read_gbq('''SELECT corpus, sum(word_count) words FROM [bigquery-public-data:samples.shakespeare] GROUP BY co...

BooleanQuery is used to combine other queries. They can be combined using three BooleanClause.Occur parameters: BooleanClause.Occur.MUST - The subquery must be matched. BooleanClause.Occur.SHOULD - The subquery may not be matched, but will be scored more highly if it is. If there are no MUST...

PhraseQuery is used to search for a sequence of terms. The following matches the phrase "Hello World" (after being indexed with StandardAnalyzer) Query query = new PhraseQuery.Builder() .add(new Term("text", "hello")) .add(new Term("text"...

This combines queries such that the best (that is, highest-scoring) match of it's subqueries contributes to the final score. List<Query> disjuncts = new ArrayList<Query>(); disjuncts.add(new TermQuery(new Term("fieldname", "hello"))); disjuncts.add(new TermQuery(...

A query can be boosted to increase it's score relative to other subqueries. This is done by wrapping it with a BoostQuery Query lessRelevantQuery = new TermQuery(new Term("fieldname", "ipsum")); //Five times as interesting Query highlyRelevantQuery = new BoostQuery( ...

When a table has an AUTO_INCREMENT PRIMARY KEY, normally one does not insert into that column. Instead, specify all the other columns, then ask what the new id was. CREATE TABLE t ( id SMALLINT UNSIGNED AUTO_INCREMENT NOT NULL, this ..., that ..., PRIMARY KEY(id) ); INSERT I...

Colored text can be created by passing the text and a font color name to the following function: private String getColoredSpanned(String text, String color) { String input = "<font color=" + color + ">" + text + "</font>"; return input; } The ...

PostScript is a Turing-complete general programming language, designed and developed by Adobe Systems. Many of the ideas which blossomed in PostScript had been cultivated in projects for Xerox and Evans & Sutherland. Its main real-world application historically is as a page description language...
