The invention concerns a method implemented by computer means for visualizing at least a zone of an object in at least one interface, said method comprising the following steps: obtaining at least one image of said zone, said image comprising at least one channel, said image being a 2-dimensional or 3-dimensional image comprising pixels or voxels, a value being associated to each channel of each pixel or voxel of said image, a representation of said image being displayed in the interface, obtaining at least one annotation from a user, said annotation defining a group of selected pixels or voxels of said image, calculating a transfer function based on said selected pixels or voxels and applying said transfer function to the values of each channel of the image, updating said representation of the image in the interface, in which the colour and the transparency of the pixels or voxels of said representation are dependent on the transfer function.

A method and device for locating an emitting source of which measurements of emission propagation at locations different from that of the emitting source can be obtained from those locations, lacking space perception, using a sensor mobile along a self-generated path. After having obtained an emission propagation measurement from the mobile sensor at the mobile sensor location, a free energy variation for moving the sensor from its current location to each of plural possible next locations of the mobile sensor is computed, the free energy being computed as a function of a standardized projected probability field of the location of the diffusing source based on previous emission propagation measurements obtained along the self-generated path. A minimum free energy variation value amongst the computed free energy variations is determined and the location associated with the determined minimum free energy variation is identified as being the next location of the sensor.
