Node image tools (Image processing on instructions from data (node) file)

Implemented: Read, Write, Blur, Sharpen,Color Correct, Size, Rotate, Composite

Used: Python 2.7 , PIL, the Python Image Library: http://www.pythonware.com/products/pil/ ,
Numpy/Scipy: http://www.numpy.org/

Node refers to the node processor to data ("link" : "read_01"). Nodes are sorted by id.

Node list

Read:

"nodeN":{

"name" : "read_01",

"type" : "read",

"file" : "read_file_name.jpg",

"id": 1

}

Write:

"nodeN":{

"name" : "write_01",

"type" : "write",

"link" : "read_01",

"file" : "write_file_name,

"id": 2

}

View:

"nodeN":{

"name" : "view_01",

"type" : "view",

"link" : "read_01",

"id": 3

}

Gradient:

"nodeN":{

"name" : "gradient_01",

"type" : "gradient",

"width" : 1280,

"height" :720,

"id": 3

}

Size:

"nodeN":{

"name" : "size_01",

"type" : "size",

"link" : "read_01"",

"size" : 1.2,

"id": 4

}

Blur/Sharpen:

"nodeN":{

"name" : "blur_01",

"type" : "blur",

"link" : "read_01",

"size" : 10,

"id": 2

}

Color Correct:

"nodeN":{

"name" : "color_correct_01",

"type" : "cc",

"link" : "read_01",

"bright" : 1.2,

"contrast":2,

"id": 2

}

Invert:

"nodeN":{

"name" : "invert_01",

"type" : "invert",

"link" : "read_01",

"id": 2

}

Rotate:

nodeN":{

"name" : "rotate_01",

"type" : "rotate",

"link" : "read_01",

"angle" : 90,

"id": 3

}

Composite: (job: plus, minus,multiply,mask,over)

nodeN":{

"name" : "composite_01",

"type" : "composite",

"link_a" : "read_01",

"link_b" : "read_02",

"mask" : "mask_01",

"job" : "plus",

"id": 3

}

Sample node files (test.json):

{

"node1":{

"name" : "read_01",

"type" : "read",

"file" : "in.jpg",

"id": 1

},

"node2":{

"name" : "blur_01",

"type" : "blur",

"link" : "read_01",

"size" : 10,

"id": 2

},

"node3":{

"name" : "write_01",

"type" : "write",

"link" : "blur_01",

"file" : "test.jpg",

"id": 3

}

}
