Add Value to Core Image Filter using Swift

Asked 2021-May-25 at 14:34

I am using CIImage to add a number of different filter types to an image. All filters are working fine with their default values, plus the CIPixellate and CICrystallize filters are working with kCIInputScaleKey and kCIInputRadiusKey values added respectfully. Howsever I am having trouble adding values for the CILineOverlay filter. I would like to feed it a specific value for inputEdgeIntensity. The Core Image Filter Reference docs state:

inputEdgeIntensity: An NSNumber object whose attribute type is CIAttributeTypeScalar and whose display name is Edge Intensity.

Default value: 1.00

But I can't find an example anywhere of how to add this value using swift. Using this code does not work:

The constant kCIInputIntensityKey maps to "inputIntensity", but you want to set "inputEdgeIntensity". You should be able to do this like that:

QUESTION

What is an XOR filter?

Asked 2021-May-13 at 23:49

There's a relatively new data structure (2020) called the XOR filter that's being used as a replacement for a Bloom filter.

What is an XOR filter? What advantages does it offer over the Bloom filter? And how does it work?

...

ANSWER

Answered 2021-May-13 at 23:49

An XOR filter is designed as a drop-in replacement for a Bloom filter in the case where all the items to store in the filter are known in advance. Like the Bloom filter, it represents an approximation of a set where false negatives are not allowed, but false positives are.

Like a Bloom filter, an XOR filter stores a large array of bits. Unlike a Bloom filter, though, where we think of each bit as being its own array slot, in an XOR filter the bits are grouped together into L-bit sequences, for some parameter L we'll pick later. For example, an XOR filter might look like this:

Datatable (DT) Shiny R - Custom SearchPane from comma-separated string

Asked 2021-May-08 at 07:45

I'm trying to create a DT SearchPanes custom filter that treats a column that is a comma-separated string as separate entries. I know how to make this work in Datatables (see here), but I'm struggling with using the proper syntax to get it to work in DT (this post was helpful, but isn't quite getting me there).

When I run the app I get an empty SearchPane that says "no data available in table."

Here's my code. I'm pretty new to DT (and Javascript), so I'm wondering if I'm missing something obvious? Any help would be greatly appreciated!

JavaScript base64string -> binary values -> [Integer] ... performance improvement

Asked 2021-Apr-17 at 08:17

I am working with Parse Server and am trying to speed up queries that use a bloom filter.

Each document has a field bf with number value in range 0...bloomSize, for example document Id "xyz" is hashed as bf = 6462

The query then loads binary bloom filter values that are encoded and saved in base64 string. To make use of indexed query in Parse Server / MongoDB I need to generate an array of integers that I can compare then with the above mentioned field. So the base64 string needs to be decoded and for each 0 in binary data I have to append an integer of that 0 value position. Currently I am using following snippet:

GLSL In ThreeJS Mix FragColor With UnrealBloom To Get Selective Glow

I want to implement selective bloom for an imported GLTF model in ThreeJS using an Emission map.

To achieve this I am supposed to first make the objects that should not have bloom completely black and using the UnrealBloomPass and the ShaderPass I'm going to mix the bloomed and non-bloomed effect passes together somehow.

I need to use GLSL code, which I'm only barely familiar with. Here is my basic setup:

The order for selective bloom is still the same:

Make all non-bloomed objects totally black
Render the scene with bloomComposer
Restore materials/colors to previous
Render the scene with finalComposer

Patch model's material, having a common uniform, that indicates which render will be used:
